Abstract
The effects of circle canyon and crack on the dynamic stress intensity factor (DSIF) and the scattering of SH-wave are studied with Green's function. A suitable Green's function is constructed first, which is the solution of displacement fields for elastic half space with circle canyon under output-plane harmonic line loading at horizontal surface. Then the integral equation for determining the unknown forces in the problem can be changed into the algebraic one and solved numerically so that crack DSIF can be determined. Last when the medium parameters are altered, the influence of the displacement between circle canyon and crack on the crack DSIF is discussed.
