Modeling crack in orthotropic media using a coupled finite element and partition of unity methods

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

“…This is despite the fact that such a method, which has been shown to perform efficiently for damage tolerance assessment of complex structures [16], [17], [18] and also holds promise for the analysis of the durability of composite materials by virtue of its ability to describe arbitrary crack growth without remeshing and with relatively coarse meshes. The most significant contributions in the area of orthotropic materials have come from [19], [20], [21] who developed new crack tip enrichment functions to effectively capture the crack tip displacement fields within linear elastic orthotropic materials. Further developments in dynamics allowed the study of propagation in orthotropic materials using XFEM [22].…”

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.…”

A Finite Element Model to Predict Wellbore Fracture Pressure with Acid Damage

“…Hu et al (2003) provided a method to calculate fracture pressure in perforated wells by FEM. Asadpourea et al (2006) provided an extended finite element method to model a crack growth in 2D orthotropic media. Besides, they have testified that the FEM was suitable for modelling and analyzing crack domain primary factors.…”
