The dynamic anti-plane problems of extension of cracks due to tearing
of an elastic wedge have been solved using the self-similarity techniq
ue. The shear stress in the plane of the cracks and the stress intensi
ty factors have been determined. Numerical results showing the variati
on of stress intensity factors with the parameters used in the problem
have been presented in tables. Copyright (C) 1996 Elsevier Science Lt
