Summary
This paper presents new finite elements with embedded strong discontinuities for the modeling of failure in solids. The new elements consider linear interpolations of the displacement jumps, leading to approximations free of stress locking in general displacement, mixed, assumed and enhanced strain quadrilateral elements. The new interpolations allow also the formulation of globally continuous interpolations along the discontinuity path as developed in this paper too. Several numerical examples are presented to illustrate the performance of the new formulations.
