A localization capturing FE-interface based on regularized strong discontinuities at large inelastic strains

objective of this work is the development of a ®nite element interface formulation tailored to capture localization within geometrically nonlinear solid mechanics. In this context, strong discontinuities are considered as the ®nal failure mechanism within localization problems. The failure kinematics are governed by a jump in the nonlinear deformation map across a discontinuity surface. In the ®nite element discretization the interface element is endowed with these kinematics. As a consequence, the interface sti€ness is dominated by the weighted spatial localization tensor. Based on these developments a localization capturing procedure is advocated and is computationally highlighted
