Effects of arbitrary holes/voids on crack growth using local mesh refinement adaptive XIGA

This paper is devoted to numerical investigation of holes/voids effects on crack growth in solids using a locally refined (LR) B-splines extended isogeometric analysis (XIGA). We particularly focus our attention on crack-hole interaction analysis. Special enrichment functions captured discontinuity and singularity are used, by which the computational mesh is thus independent of both cracks and holes, eliminating re-meshing when modeling crack...
