节选段落一：
Extended FEM (XFEM) implementation of the CZM based discontinuous approach
In this section the XFEM implementation of the CZM based discontinuous approach is addressed. In particular, the
improved stable XFEM (is-XFEM) developed by the author (Wu and Li, 2015a) for cohesive fracture is considered.节选段落二：
More recently, the author (Wu and Li, 2015a) developed an improved stable XFEM (is-XFEM)
in which the Heaviside enrichment function is perturbed by its linear interpolant.节选段落三：
The case cs D 0 recovers the Heaviside enrichment function used in the standard
XFEM, and cs D 1 corresponds exactly to the stabilized XFEM introduced in Babuška and Banerjee (2012).
