Abstract

The purpose of this investigation is to propose a numerical simulation method of the crack propagation behavior in 3D elastic body. The simulation method is based on the displacement-type finite element method, and the linear fracture theory is introduced. The results from the proposed method are compared with those from the structural experiments, and the good coincidences between them are shown in this paper. At the same time, 2-dimensional analysis is also done, and the results are compared with those obtained from 3-dimensional analysis and the structural experiments.

Key Words

linear fracture theory ; FEM; 3D crack propagation; automatic mesh generation; singular isoparametric element.
