Abstract: A nearly non-spurious oscillations explicit time integration scheme for finite element solution of linear and non-linear wave propagation of stress discontinuities in solids and contact problems is presented and tested. The main concept of the diminishing spurious oscillations time scheme is based on a modification of the conventional central difference method.
Keywords: contact problem, finite element method; dispersion, spurious oscillations; elastic and non-linear wave propagation; explicit time integration
