Popis:	The eXtended Finite Element Method (XFEM) has been successfully used for several years for the numerical analysis of cracked structures under statically and later under dynamically loadings. Based on Partition of Unity Method, the XFEM was developed at Northwestern University (Moes et al. [1]) firstly as a method for analysing crack growth without remeshing, using special enrichment functions to model discontinuous displacement fields. Since, the method was continuously improved and applied to various domains of fracture mechanics. The dynamic crack propagation is one of them and an important contribution for its modelling by XFEM was given by Belytschko et al. [2].
