## Abstract This paper is concerned with developing a numerical tool for detecting instabilities in elastoโplastic solids (with an emphasis on soils) and inserting a discontinuity at these instabilities allowing the boundary value problem to proceed beyond these instabilities. This consists of impl

## Abstract Based on the finiteโelement approximation and nonoverlapping domain decomposition, an efficient tearing and interconnecting algorithm of the finiteโelement timeโdomain method is presented. Using edgeโbased finite element, the method divides the computation domain into several nonoverlap
The introduction of discontinuous/non-differentiable functions in the eXtended Finite-Element Method allows to model discontinuities independent of the mesh structure. However, to compute the stiffness matrix of the elements intersected by the discontinuity, a subdivision of the elements into quadra
