Application of BEM to Two-Dimensional EPFM

by Al Ghorbanpoor, Univ of Wisconsin-Milwaukee, United States,
Jiping Zhang, Univ of Wisconsin-Milwaukee, United States,



Document Type: Proceeding Paper

Part of: Structural Materials

Abstract:

This paper describes the authors' current and continuing research in application of the Boundary Element Method (BEM) to crack growth problems in Elastoplastic Fracture Mechanics (EPFM). Two types of crack propagation, Mode I type crack growth and the mixed mode crack propagation, are studied in this work. In conjunction with the Crack Tip Opening Displacement (CTOD) or the Crack Tip Opening Angle (CTOA) criterion, the stationary crack growth for ductile materials is predicted for the mode I loading.
