Symmetry preserving algorithm for a dynamic contact-impact problem
A three dimensional contact-impact algorithm based on the pre-discretization penalty method is presented. It is shown that the proposed method preserves a symmetric treatment of mutually contacting surfaces. The symmetry of the algorithm is tested by...
