Within the framework of this research project, a material model will be developed based on suitable multiaxial experiments, which can meet the high demands of heuristic structural optimization under dynamic loads, in particular under the most varied loads possible
Due to their anisotropic behavior and their specific failure modes, the calculation and design of fiber reinforced plastics pose a great challenge to the used calculation methods, even in the static load cases. This is particularly evident when structural optimization methods are being used, since the calculation must reliably distinguish between promising designs and inferior designs. In the optimization of crash or dynamically loaded structures, the calculation of the nonlinear behavior of these structures in almost all areas becomes even more demanding. This means that classical optimization methods can only be used to a limited extent. Instead, experience-based, heuristic methods represent a promising alternative, since they can work better with strong nonlinearities. However, since these optimization methods can only be as good as the quality of the individual calculations, a suitable robust material model must support solution finding. This makes a complex experimental characterization of the material with suitable test methods inevitable.
