A consistent iterative scheme for 2D and 3D cohesive crack analysis in XFEM
A two-dimensional subspace is constructed to perform calculations related to cohesive tractions. A simple and effective way to transform quantities from subspace to global three-dimensional space is presented. In the presented approach, cohesion laws connected with crack opening, crack sliding and their mixture can be applied easily. Special attention is given to consistent linearization of the transformation.
