I'm currently working my thesis about ballistic impact on composites plate. I have no idea about the most efficient and computationally inexpensive way to model composites structure using solid elements. I've googled some papers that discusses about this topic (including LS-DYNA user manual), but I still found those information inadequate for me. I've read about the tiebreak contact as well as cohesive element and still can't get the puzzle right.
I would appreciate it if somebody can give me some detail explanation about this topic.
