| Résumé: | This study is dedicated to solve material interface problems using the extended isogeometric analysis (XIGA). Non-uniform rational B-splines (NURBS) are used as shape functions for the interpolation, and also for describing the geometrical domains. Two types of enrichment functions are used in the framework of the XIGA. The first one is suitable for modelling strong discontinuities and the second one is suitable for modelling weak discontinuities. Knot insertion and order elevation refinement methods are applied to improve the accuracy of the results. The stress intensity factors (SIFs) in two modes are computed by the interaction integral approach in order to evaluate the state of the interfacial cracks |
