Abstract
A steady wave process is considered in the half-space with tunnel-like curvilinear cracks under conditions of antiplane deformation. The ensuing boundary value problems are reduced to singular integro-differential equations which are realized numerically. If the crack tip reaches the half-space boundary, the kernel of the integrodifferential equation contains, besides a moving singularity of the Cauchy type, a fixed singularity, and this singificantly affects the pattern of longitudinal shear stress wave fields. This case is the subject of detailed investigation below. Certain singularities of such wave processes are pointed out, and the results of calculations of the dynamic stress intensity coefficient are presented.
