Dynamic Propagation of Asymmetrical Mode Ⅲ Interface Crack

By the methods of the theory of complex functions, dynamic propagation problems concerning asymmetrical mode Ⅲ interface crack are studied. Asymmetrical dynamic propagation problems under the action of variable loads （Px/t） and （P³t/x²） located at the origin of the coordinates respectively, are resolved by the measures of self-similar functions, and the universal expressions of analytical solutions to stresses, displacements and stress intensity factors are gained. The variational rule of dynamic stress intensity factors is illustrated by the approaches of numerical computations, and the result obtained is coincident with relevant literatures.
