摘要：
Most works in the literature on interactions of cracks and stress waves were for collinear or parallel cracks. However, in reality, cracks are usually randomly oriented. In this work, the problem of a homogeneous linear elastic body containing arbitrarily oriented cracks under dynamic antiplane shear loading is considered. Distribution of dynamic dislocations is used to simulate the cracks and the corresponding integral equation is derived. The integral equation is utilized to calculate the dynamic stress intensity factors. Numerical examples are provided to demonstrate the effectiveness of the present method.
