Adaptive remeshing in transient impact processes with large deformations and nonlinear material behavior

The present study is concerned with impact processes that appear in civil and military security technology, dynamic soil compaction, vehicle crash or fastening and demolition technology. They are characterized by varying non-linearities, as e.g. large deformations and strains, highly non-linear material behavior, frictional contact between multiple bodies and stress wave propagation. A combination of different methods in adaptivity, constitutive modeling, element technology, efficient time discretization and contact are essential for the reliable computation of practical relevant engineering tasks and for predictions in industrial applications. Accuracy, robustness and efficiency are the authoritative requirements for the solution of those complex problems.
