A Topology Optimization Tool for LS-DYNA Users: LS-OPT/Topology: Topology optimization is a very powerful tool to develop new concepts an has widely used in engineering problems involving static loading conditions. However, there has been relatively little work for topology optimization of industrial size non-linear dynamic systems. The main issues are non-linear interactions among the material properties, contacts between parts, large strain-rates, transient behavior, etc. A hybrid cellular automata based method, combining cellular automata theory with the fully loaded...
