抄録

The extended finite element method (X-FEM) is applied to three-dimensional elastic-plastic crack problems. The developed X-FEM code uses 8-node hexahedral finite elements and the level set method to model a planar crack with various geometry independently of the finite element and can perform static analysis considering the elastic-plastic constitutive equations and evaluate the J-integral at the crack front by the domain integral method. Moreover the ductile crack propagation simulation can be performed by executing the elastic-plastic analysis code successively. In this paper the outline of the developed system and results for semi-elliptical planar crack in a plate is shown.
