| Abstract: | In this paper the functionally invariant solution of the wave equation of anti-plane problems in the orthotropic material is obtained. On the basic of this solution, a complete solution for anti-plane elasticity dynamic problems with an arbitrary index of self-similarity in the orthotropic body is given. Using conditions of interface and the complete solution, the shock problem of propagating crack in interface between different orthotropic media can be changed into the Keldysh-Sedov mixed problem of theory of analytic functions. In the paper, the closed solution of this problem is given. Using this solution, we have analysed effect to the dynamic stress intensity factor by the constant of media and the velocity of crack propagation. |
