✦ Synopsis

The use of a discontinuous Galerkin (DG) formulation for the solution of elasto-dynamic problems with discontinuities in the displacement gradients is examined. Comparisons with exact solutions are presented. The paper demonstrates that space-time finite element methods based on a DG formulation can be very effective in the study of dynamic solid/solid phase transitions as well as dynamic fracture.

## Abstract In this paper two plane strain quadrilateral elements with two and four variables, are proposed. These elements are applied to the analysis of finite strain elasto‐plastic problems. The elements are based on the enhanced strain and B‐bar methodologies and possess a stabilizing term. The

A functional has been developed for the finite element solution of diffusion-convection problems. This functional is suitable for the application of the variational principle on discretization schemes in the spacetime domain. This algorithm has shown to be computationally efficient over the conventi
