Abstract: Dynamic propagation of asymmetrical mode III interface crack were investigated with the theory of complex functions. It can be translated into a Riemann-Hilbert problem by means of self-similar functions, and the universal representations of analytical solution were obtained when there is $Pt / x$ or $Px^3 / t^2$ load at the origin of the crack coordinates. The closed-form solutions can also be simply obtained with Muskhelishvili's theory.

Key words: complex functions, asymmetrical mode III interface crack, dynamic problems, self-similar functions, analytical solutions
