Orthotropic Enriched Extended Isogeometric Analysis for Fracture Analysis of Composites

Fracture analysis of orthotropic cracked plates is investigated by applying the recently developed computational approach, called the extended isogeometric analysis (XIGA) [1]. A signed distance function and orthotropic crack tip enrichment functions are adopted for extrinsically enriching the conventional isogeometric analysis approximation for the representation of significant discontinuities and reproducing the singular field around a crack...
