An unbiased self-contact formulation for explicit FEA stabilized by the bipenalty method
Original language description
In the explicit finite element analysis (FEA), contact boundary conditions are often enforced by the penalty method. However, it is well known that the penalty parameter negatively affects the size of the critical time step of the explicit time integration scheme. A remedy to this issue could provide the bipenalty method. Recently, promising results for 1D contact-impact problems have con rmed this idea. Therefore,further development and testing for higher spatial dimensions followed. The objective of this contribution is to present the energy conservation properties of the bipenalty method and thus to prove the suitability of this approach for solving the explicit FEA contact-impact problems. To this end, a symmetry preserving contact algorithm has been modifed to consider self-contact. Several numerical examples will be presented to demonstrate the performance of the proposed contact algorithm.
