Micro Abstract:
In this contribution a primal discontinuous Petrov Galerkin Finite Element Method (dPG FEM) with a linear elastic isotropic material model is presented. This novel mixed discretization method was introduced by Demkowicz and Gopalakrishnan in 2010. The behavior of this formulation is studied with benchmark simulations for small deformations in the nearly incompressible case. Furthermore, a possible extension for a nonlinear Finite Element formulation is suggested.
