Extended nite element method for three-dimensional crack modelling
An extended nite element method (X-FEM) for three-dimensional crack modelling is described. A discontinuous function and the two-dimensional asymptotic crack-tip displacement elds are added to the nite element approximation to account for the crack using the notion of partition of unity. This enables the domain to be modelled by nite elements with no explicit meshing of the crack surfaces. Comp...
متن کاملExtended finite element method and fast marching method for three-dimensional fatigue crack propagation
A numerical technique for planar three-dimensional fatigue crack growth simulations is proposed. The new technique couples the extended finite element method (X-FEM) to the fast marching method (FMM). In the X-FEM, a discontinuous function and the two-dimensional asymptotic crack-tip displacement fields are added to the finite element approximation to account for the crack using the notion of p...
متن کاملExtended Finite Element Method for Fretting Fatigue Crack Propagation
In this paper, the extended finite element method (X-FEM) is considered for the analysis of fretting fatigue problems. A two-dimensional implementation of the XFEM is carried out within the finite element software ABAQUS by means of user subroutines, and crack propagation in fretting fatigue problems is investigated. On utilizing the non-linear contact capabilities of this code, the numerical t...
متن کاملSimulating energy method for grout-induced crack analysis of rock structures at Chadormalu mine by extended finite element method
Fracture mechanics is a vital component involved in studying the exact behavior of rock materials. Detection and assessment of the behavior of rock joints injected by grout plays an important role in numerical modelling in rock mechanic projects. The importance of mechanisms associated with initiation and propagation of cracks due to hydraulic fracturing has led to a considerable interest in in...
متن کاملPrediction of Crack Initiation Direction for Inclined Crack Under Biaxial Loading by Finite Element Method
This paper presents a simple method based on strain energy density criterion to study the crack initiation angle by finite element method under biaxial loading condition. The crack surface relative displacement method is used to eliminate the calculation of the stress intensity factors which are normally required. The analysis is performed using higher order four node quadrilateral element. The...
