Multi-scale approach for new design solutions in automotive applications
The increased demand for new generation of vehicles desperately requires the development of light, tough, high strength components which can withstand the modern demands for cost effectiveness, safety and ecosustanaibility. Such a result can be achieved by a new simultaneous engineering & manufacturing approach, which is Intelligent Processing, basically consisting of
  • New and integrated multi-scale (Nano-, Micro- and Macro-scale = NM2) simultaneous engineering tools, to optimise the use of materials to produce multifunctional components;
  • Deeper knowledge (from nano- to macro-scale) about the materials (effects and interactions of alloying elements, criteria for selection of processes and alloys, new/innovated/low-cost light alloys, selected manufacturing processes);
  • Extensive use of simultaneous engineering, to develop/produce high tech components by the intelligent use of nano/micro technologies, multifunctional materials and casting processes.

Intelligent Processing approach can lead to excellent results when applied to light alloys (i.e. Al- and Mg- based alloys), which, if properly used by automotive engineers and designers, can satisfy mechanical, aesthetics, ecological and functional requirements with a substantial weight reduction and a potential reduction of the number of components.
The papers presents the development of intelligent processing systems to produce multifunctional, high-tech, integrated components for EU transport, carried out in the frame of NADIA (New Automotive components Designed for and manufactured by Intelligent processing of light Alloys) Project. After a general description of the multi-scale concepts applied to light alloys casting processes, the key-role of the correlations among microstructural parameters, numerical simulation and mechanical behaviour of the cast alloys, in view of the innovative design of automotive components, is highlighted.

Aerospace sheet metal flattening based on energy models
This paper presents a method for three-dimensional surface flattening, to be used in three dimensional sheet metal forming aerospace applications.
The method presented here can efficiently solve flattening problems for complex surfaces in aerospace industry applications.
Stl model from some CAD software is firstly imported to get the complex surfaces. Then, spring-mass models based on energy function are used to flatten the 3D mesh surfaces into 2D patterns.
The countured surface elastic deformation energy distribution can be displayed, and surface cutting lines can be determined to reduce distortion. The accuracy of a developed surface can be controlled locally.
Thus, compared to earlier methods, this method provides more flexibility for solving CAD and CAM problems.

The CAX systems as enabling instruments for automotive innovation
The development of new automotive products is influenced by the following items: Market evolution and changes; New Competitors; Wide range of Products (Fragmentation); Technology mix (Mechanical/Electronics); World Wide Competition; Availability of new competitive components during life cycles; Alliances/ Share of Components-Systems/ Share of Production Sites; Innovation vs. Risks and Competitiveness. Furthermore there are a lot of difficulties to foresee the performance scenarios for a temporal range of about 8 years (i.e. Aerodynamics or Safety). Marketing asks to the customer for a big effort of imagination (about 6 years). To face these problems we have to adopt new approaches for the future product development, in particular we require the development of tools and methodologies that enable the:

  • Product Engineering to explore several possible solutions, produce realistic product evaluations (customer point of view), accurate simulation of product performances and an efficient Products Lifecycle Management
  • Process Engineering to produce reliable feasibility studies, estimation of time and methods operations, Operator Comfort evaluation, time and quality optimization for the production line

The methodologies based on the CAx tools allow to:

  • Simulate digitally the whole Product and Process in order to reduce the risk in the decisional process during the product development.
  • Evaluate the Product (Functions and Process view) digitally without building PMU and reducing the amount of design validation by means of hardware.

These methods contribute to reach a competitive Time To Market (world class), to explore a wide range of alternative solutions for the new model, to execute a Performance Optimisation and finally to obtain a high confidence decisional process for technical and customer specifications in a clear competitive scenario.

A simulation based diagnostic system for the abdominal aortic aneurysm
Abdominal aortic aneurysms (AAAs) are pathological enlargements of the aorta in the stomach area and represent a significant health problem worldwide, not least because of the ageing population. AAAs constitute examples of expansive vascular remodeling, the natural history of which includes progressive enlargement, and possible rupture if left untreated.
Intervention is indicated by the likelihood of aneurysm rupture, which is, according to the current clinical practice, estimated from the formation's maximum diameter and/or expansion rate. Although this rupture risk assessments works relatively well in general, it is known to fail often in individual patients, and hence under controversial clinical and scientific discussions.
Accurate rupture risk assessment is critical to avoid unnecessary interventions, and recent research demonstrated that patient specific computer simulations can provide reliable indications of aneurysm rupture. Likewise, detailed biomechanical simulations might provide field variables particularly useful to uncover mechanisms of AAA genesis and enlargement in general. The present paper demonstrates the development of a simulation based diagnostic system for routinely clinical applications. The integration of especially developed segmentation techniques and grid generation algorithms enables fast derivation of structural and hemodynamic models of patient specific formations. Results achieved with the proposed system underline its clinical applicability, and apart from that the system facilitates fast and detailed investigations of vascular lesions in general, a requirement for a fundamental pathological understanding of cardiovascular diseases.

Inverse Analysis Procedures for Mechanical Characterization of Materials and Diagnosis of Structures
The main practical purpose of computational mechanics is to provide methods and tools for predictive simulations of the responses of structural systems to external actions. In many engineering applications, especially to possibly damaged existing structures, a crucial requirement for reliable modelling is a realistic and accurate input in terms of constitutive models and relevant parameters.
This communication is intended to evidence practical advantages provided by innovative synergistic combinations of experiments and their computer modelling for the assessment of (possibly deteriorated) material properties through minimization of a suitable discrepancy norm between measured quantities and their counterparts computed as implicit functions of the sought parameters.
Such minimization (often non convex and nonsmooth) can be performed either by traditional mathematical programming algorithms, or, as a recent development, by soft computing.
In this context soft computing includes evolutionary genetic algorithms and artificial neural networks. Artificial neural networks (suitably trained and tested, once for all) and the novel technique called "proper orthogonal decomposition" provide computational tools for inexpensive and robust inverse analyses susceptible to be carried out in situ by small computers.
The applications to real-life engineering problems presented as illustrative examples concern steel components of industrial plants (pipelines for example), micromechanical devices and large concrete dams.

Analysis of Vibration Phenomena in Solar Receivers of Parabolic-Trough Concentrators, induced by Pressure and Flow Rate Variations of yhe Refrigeration Fluid and the Solar Flux, by a Nonlinear Dynamics Approach
Absorbing tubes covered by selective coating suitably insulated from surrounding environment and located in focal position, are used as absorbing system of the mirror concentrated radiation in solar trough power plants based on parabolic-trough collector systems. During one of the tests on commercial receivers conducted at ENEA PCS plant, the setting of a vibration phenomenon of the line has been observed for the time period of maximum insulation, particularly severe in a specific receiver. Such a vibration, de-focalizing the collector but maintaining the refrigerating fluid in motion, is rapidly damped. In this paper a numerically based work to minimise or even eliminate the occurrence of such vibration phenomenon, dangerous for the insulating coat of the receiver, is presented. Gravitational load and transverse thermal gradient induce a bending deformation of the line, which is sensible to the pressure variation and to the fluid flow rate, due the circulation pump and to the valves. Moreover, the consequent oscillation should alter the flux impacting on the receiver with a further variation of the transverse thermal gradient on the line. First of all it has been performed an estimate of the frequencies of vibration and related modal shapes of the line; then a linear dynamic model has been developed based on Newmark algorithm, evaluating step-by-step the stresses induced by the fluid as a function of the local curvature. Such a model has been implemented in Cast3m finite element code. Sinusoidal variations of the fluid velocity and pressure have been assumed in the analyses. It has been posed a particular attention to the space-time discretization and to the damping. The obtained results show how even small flow rate and pressure variations are able to activate the vibration and more sensibly as far as the transverse thermal gradient increases. However, an underestimation of the maximum amplitude results and this induced to deeply investigate on the aspects not yet modelled. In this context, a more general approach has been selected, based on a fully nonlinear dynamic beam theories, allowing for the study of the mechanical behaviour of systems of beams based on the hypotheses of large strains, displacements and rotations. The approach is based on the imposition of the equilibrium in functional form, employing linearization procedures leading to geometrical and material tangent stiffness. Such a procedure allowed to obtain a more realistic reconstruction of the observed phenomena in the absorbing pipes of the solar trough power system.

A major part of his current research is the effect of ship airwakes on helicopter-ship operations; this work is supported by UK Research Councils, the UK Ministry of Defence, and AgustaWestland.

Virtual Engineering of the Helicopter-Ship Dynamic Interface
This paper is concerned with simulating the highly dangerous and demanding task of landing a helicopter onto a ship at sea. The helicopter flight dynamics has been modelled using a multi-body dynamics modelling and simulation environment. The unsteady complex air flow over the ship'' superstructure is modelled using Computational Fluid Dynamics, taking into account a realistic ship geometry, the Earth's bundary layer, and different wind strengths and directions. The helicopter flight dynamics and the airwake are brought together in a motion-base flight simulator which allows a pilot to land a helicopter onto a ship under conditions that are shown to be highly representative of the real experience, holding out the prospect that flight simulation can be used to determine the at-sea conditions under which it is safe to land a helicopter on a ship, and to also provide a safe and realistic environment for pilot training.

Computational mechanics simulations of the forming process of carton packages for beverages
Food packaging is a fast growing industry, addressing a very basic demand for safe and economical food distribution, driven in developing countries by an increase in availability and spending power, and in the North American and Western European markets by a demand for both healthy and convenient packaged food, as well as premium foods. Among the different types of packaged foods, a prominent place is occupied by carton packaged beverages. In 2007 Tetra Pak, the leading company in this market, delivered more than 137 billion packages worldwide ? that?s 4344 packages of food or drink each second.
Growing competition and increasing quality standards require a continuing dedication to the development of new technologies to make the package forming process faster and safer. Nowadays, in a modern production line, almost ten thousand packages per hour are normally produced. The computer simulation of the production process is a key ingredient for the successful and economical implementation of these new technologies.
Our research activity has been focused on the numerical simulation of the mechanical process of forming carton packages for beverages. The complexity of the process involves several aspects at the frontline of the research in computational mechanics: large displacements and rotations of shells, contact, fracture, fluid structure interaction. We are currently developing a finite element tool for the simulation of the folding process of the carton web along pre-formed crease lines and for the simulation of the interaction between the container and the filling liquid.

Robust Design Optimization of Engineering Systems
The future of industrial design optimization is robust design optimization whereby a design is optimized for real world conditions and not just for one particular set of idealised nominal conditions. There is no practical point trying to get to the peak of a mountain to get the best view when a slight gust of wind can blow you off. A practical strategy would be to find the highest little plateau where, on the one hand, the view is unaffected and, on the other hand, you have enough space not to lose your footing. The same is true for engineering design: there is no point in coming up with a design which is optimized for a set of ideal conditions when in reality there exists uncertainty in the materials, manufacturing and operating conditions. This presentation gives an overview of techniques used for simultaneous optimization of the robustness of a design and its performance which is similar to finding the plateau (that lies as high as possible) rather than the peak.

In many industrial applications a direct application of Monte Carlo simulation linked to a high fidelity simulation would be prohibitively computationally expensive. Therefore, a practical process is suggested that is based on

  • creation of metamodels of the responses defining the optimization problem as functions of design variables and uncontrollable (stochastic) variables,
  • check of their quality and
  • use of them for both solving an optimization problem and the Monte Carlo simulation within an optimization run.

The stochastic optimization process is illustrated by several examples including:

  • demonstration of the design optimisation and probabilistic assessment of a vented airbag landing system for the ExoMars space mission 2013
  • design of an automotive knee bolster system where the design is optimized to account for different sized occupants, impact locations, material variation and manufacturing variation.

The Future of CAE in computer aided medicine: the Virtual Physiological Human initiative
The current CAE technology has been developed to solve the problems of a few reference industries (aerospace, automotive). In the last few years some effort are being made by leading companies to tackle new markets by developing products that are specialised on the needs of that particular industrial segment. The scope of this presentation is to critically revise the available CAE technologies and to suggest possible directions to make them more effective in the context of computer aided medicine. This will be done firstly targeting conventional biomechanics modelling problems such as the design of implantable medical devices, or body-level or organ-level biomechanical modelling. Secondly we shall describe the new challenges that are emerging from the so-called Virtual Physiological Human (VPH) initiative, with particular reference to multiscale modelling, and interdisciplinary postprocessing.
We shall show that while the first group of applications can be addressed by ?evolutionary? tools, obtained by adapting current CAE technology in combination with some domain-specific methods, the VPH research will require ?revolutionary? tools and methods, which in the long run might even bring back innovation to industrial engineering applications.
