Abstract:
By the measures of the theory of complex functions,the dynamic propagation problems concerning mode Ⅲ asymmetrical interface crack under the action of moving variable loads are studied.The universal expressions of analytical solutions are readily attained by the technique of self-similar functions and corresponding differential and integral operation.The problem discussed here can be easily translated into Riemann-Hilbert problem by this approach,and the analytical solutions of the stress,displacement and dynamic stress intensity factor under the crack surfaces subjected to moving variable loads are respectively attained.Their closed solutions are obtained by means of Muskhelishvili’s method.The solutions of the discretionally complex problems can be gained by those solutions and superposition theorem.
