NAFEMS - INDIA Workshop on Finite Element Analysis of Composite Structures 29 & 30 March 2011 Cambridge Institute of Technology campus K.R. Puram, Bangalore Co- organisers About the Course Many designs now use composite structures or components, taking advantage of the increased structural strength and stiffness to weight ratios, simpler manufacturing process, or more innovative design capability that composites bring. The nature of the composite used can range from cheap and freely available glass fiber reinforced systems to exotic and specifically tailored carbon or kevlar systems, with many forms of manufacturing process available. The challenge for the designer and analyst is to determine the resulting stiffness and strength of the design. Faced with the complexity of real world structural systems the analyst has to make decisions on the type of idealization and level of detail required in the Finite Element Analysis. Your design may include thick composite sections with large numbers of plies, there may be regions of significant ply drop off. Tee joints may be loaded in tension. In these cases the through thickness effects become very important for strength prediction. The shape of the structure may imply changes in draping angle or layup thickness and it may be important to model this accurately. There are a wide range of failure theories, together with potentially large amounts of stress or strain data from a multi ply layup. Due to the nature of the composite the stress components can include many more terms than a conventional metallic material for example. Whatever the nature of the challenge, this objective of this course is to break down the composite analysis process into clearly defined steps, give an overview of the physics involved and show how to successfully implement practical solutions using Finite Element Analysis. Importance of course for the organizations using FEA in composite structures The salient aspects of this course are The course would be handled by very experienced industry exposed users of Finite Element Analysis in Composite Structures This course would offer vital guidance to judge which approximations are acceptable for solving the practical problems. Each participant would be provided with high quality training notes. Overall, this programme is designed to enhance the functional knowledge of young Finite Element Analysis users in the practical application of in Composite Structures. About NAFEMS NAFEMS is the International Association for the Engineering Analysis Community and it operates as an independent, not-for-profit association. The scope of its activities encompasses all simulation technology, including Finite Element Analysis, Composite and Computational Fluid Dynamics. As new application areas and techniques constantly evolve, NAFEMS becomes involved to create awareness of new analysis methodologies, deliver appropriate education and training, simulate the adoption of best practices and effective use of technology by offering a platform for continuous professional development. NAFEMS and its members are involved in the application of many different types of engineering simulation covering both products and processes. Membership exceeds 950 corporate members from over 32 different countries. Who Should Attend? This course is aimed at practicing engineers who wish to learn more about how to apply finite element techniques to composite analysis in the most effective manner. Ideally a student should have some experience of FEA analysis, but this is not essential. The material that is presented is independent of any particular software package, making it ideally suited to current and potential users of all commercial finite element software systems. This course is a must for all engineers aiming to use FEA as a reliable predictive tool for composite analysis. The course is open to both members and non-members of NAFEMS.
