Summary

A crack propagation analysis system based on the extended finite element method (XFEM) using a cohesive zone model (CZM) for 2D, quasi-3D, and 3D fracture problems was developed. In 2D and quasi-3D analyses, only the Heaviside function is used as the enrichment function. In the 3D analysis, both the Heaviside and the asymptotic basis functions are used. In all analyses, the constitutive equations for the CZM are considered at the evaluation point on the discontinuous line and plane defined by the elements. In the developed system, the explicit method is also implemented to solve the problem in which a converged solution cannot be obtained by the implicit method. This paper shows the numerical method based on the XFEM, the outline of the development system, and numerical examples for verification.
