Time-Space FE-PDAS Method for Dynamic Unilateral Contact Problem in Viscoelasticity

摘要

The paper deals with numerical analysis of a class of multi-body dynamic unilateral contact problems. The presented problem describes the seismological model problem, representing a new approach in this branch and of studying propagation of seismic waves through broken up upper parts of the Earth. The semi-implicit finite element and the primal-dual active set strategy methods will be discussed.
