Numerical simulation has become a fundamental element in the development of motor vehicles. Today, many important design decisions, especially in the field of crash, are based on simulation results. During the last few years there has been an increase in the use of foams in vehicles. These are, due to their variety and structure, much more complicated regarding the characteristics of the materials than "simple" materials such as steel or aluminum, which can be modelled rather well. .. continue reading Characterization of foam materials is a great challenge for the simulation expert. Although by now there are different modelling approaches available in explicit FEM-programs such as LS-DYNA, PAM-CRASH or RADIOSS, these are, however, often not satisfactory. The application of these special material models requires a sound knowledge and experience. The seminar provides an overview over plastics and foam materials used in automotive engineering and their phenomenology. On the first day you obtain an introduction into the simulation of elastic and visco-elastic polymers, such as elastomers and elastic polymer foams with volume elements. You are thereby coming to understand the available material models in explicit finite element programs. On the second day the focus is on the treatment of plastics, such as thermo- and duroplastics through elasto-plasticity with isotropic hardening. Non-associated deformation is going to be discussed as well. The seminar is rounded off with the procedure for simulation of glass-fiber reinforced plastics using both isotropic and anisotropic material laws. For a demonstration you are going to see examples created with the program LS-DYNA. References to material models in LS-DYNA an PAM-CRASH are going to help you in applying what you will have learnt.
