XFEM fracture analysis of orthotropic functionally graded materials

An experimental/numerical investigation into the main driving force for crack propagation in uni-directional fibre-reinforced composite laminae

“…Further developments in dynamics allowed the study of propagation in orthotropic materials using XFEM [22]. Other topical work has focussed on interlaminar delamination [23] and cracks in functionally graded composites [24], [25]. In this paper, a new tool based on the extended finite element method (XFEM) which allows to simulate the growth of arbitrary cracks in orthotropic materials is devised, analysed and validated experimentally.…”

Computation of dynamic stress intensity factors in cracked functionally graded materials using scaled boundary polygons

“…Application of the XFEM to compute the dynamic SIFs in FGMs has been reported by Motamedi and Mohammadi [18], Singh et al [19], Bayesteh and Mohammadi [20] and Liu et al [21]. To compute the stress intensity factors, additional postprocessing techniques e.g.…”

XFEM buckling analysis of cracked composite plates

“…This method has successfully been extended to several static and dynamic isotropic and orthotropic problems, as well as modeling inter laminar cracks in bi-materials [22,[28][29][30][31][32][33][34][35][36][37][38]. Recently, Nguyen-Thanh et al [39] developed an extended isogeometric shell formulation based on the Kirchhoff-Love theory.…”
