Abstract

Amixed XFEMformulation including inertia terms for the efficient, locking free simulation of cracks and heterogeneities in nearly incompressible materials under dynamic loads is presented. It is shown, that this formulation can accurately predict wave speeds and reflection patterns at heterogeneities in nearly incompressible materials for coarser meshes, than the standard XFEM element with first order shape functions.
