NUMERICAL MODELING OF DYNAMIC CRACK PROPAGATION IN FINITE BODIES, BY MOVING SINGULAR ELEMENTS -- PART II. RESULTS
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.
