摘要：

A solution is given for problems involving non-axisymmetric dynamic impact loading of a penny shaped crack in a transversely isotropic medium. Laplace and Hankel transforms are used to reduce the equations of elasticity to integral equations, and solutions are obtained;for; the three modes of fracture; The stress intensity factors are determined for a penny shaped crack loaded by; concentrated normal impact forces,and concentrated radial shear impact forces. The integral equations are solved by,numerical methods, and the results are plotted showing how the dynamic stress intensity factors are influenced by the-asymmetric loading.
