An element-free Galerkin method for three-dimensional fracture mechanics
The application of a coupled ®nite element± element-free Galerkin (EFG) method to problems in threedimensional fracture is presented. The EFG method is based on moving least square (MLS) approximations and uses only a set of nodal points and a CAD-like description of the body to formulate the discrete model. The EFG method is coupled with the ®nite element method which allows for the use of the...
متن کاملA novel modification of decouple scaled boundary finite element method in fracture mechanics problems
In fracture mechanics and failure analysis, cracked media energy and consequently stress intensity factors (SIFs) play a crucial and significant role. Based on linear elastic fracture mechanics (LEFM), the SIFs and energy of cracked media may be estimated. This study presents the novel modification of decoupled scaled boundary finite element method (DSBFEM) to model cracked media. In this metho...
متن کاملThree-dimensional Mesh-generator for Finite Element Method Applications
The finite element method (FEM) [1] is one of the most effective numeric methods for solving linear and non-linear multi-dimensional scientific and technical problems. It allows modeling of systems with a complex geometry and an irregular physical structure. One of the most time-consuming steps when solving three-dimensional problems using the FEM method is building adaptive mesh. The mesh shou...
متن کاملThree Dimensional Finite Element
Numerical modeling of electromagnetic nondestructive testing problems has become in the last few years common enough to be considered an integral part of the engineering design practice. In particular, eddy current modeling activity has been on the increase because of the benefits afforded by such models and their relative simplicity and availability. This is certainly true for two dimensional ...
متن کاملA two dimensional Simulation of crack propagation using Adaptive Finite Element Analysis
Finite element method (FEM) is one of the most famous methods which has many applications in varies studies such as the study of crack propagation in engineering structures. However, unless extremely fine meshes are employed, problem arises in accurately modelling the singular stress field in the singular element area around the crack tip. In the present study, the crack growth simulation has b...
