A three-dimensional impact-penetration algorithm with erosion. (English) Zbl 0603.73078

A new interaction algorithm for treating three-dimensional impact- penetration simulations with erosion is presented. This algorithm is based on interactions between slave nodes (projectile) and master elements (target) and no tracking of the sliding interfaces is needed. It employs an assembly of normals to identify the interface surface adaptively so that it can handle eroding elements in both the target and the penetrator. In the interaction algorithm, momentum is exchanged between interacting nodes so that the total momentum is conserved. Examples of three-dimensional calculations are also given.
