Numerical Modeling of Dynamic Crack Propagation in Finite Bodies, by Moving Singular Elements. Part II. Results.

Abstract

Using the moving-singularity finite element method described in Part I of this paper, several problems of dynamic crack propagation in finite bodies have been analysed. Discussions of the effects of wave interactions on the dynamic stress-intensity factors are presented. The obtained numerical results are compared with the corresponding infinite domain solutions and other available numerical solutions for finite domains. (Author)
