DYNAMIC STRESS INTENSITY FACTOR AND SCATTERING OF SHWAVE BY AN ELASTIC CYLINDRICAL INCLUSION AND A CRACK IN HALF SPACE

摘要：

An analytical method is developed for dynamic stress intensity factor and scattering of SH wave by a half space containing an elastic cylindrical inclusion and a crack. A suitable Green’s function is constructed, which is the fundamental solution of the displacement field for a half space with an elastic cylindrical inclusion impacted by an out-plane harmonic line source loading at an arbitrary point in half space. And then a crack in any position and direction can be constructed in half space by means of crack-division which is expressed in terms of the Green’s function. Moreover, the displacement field and stress field are established in the case of coexistence of elastic cylindrical inclusion and crack. The expression of dynamic stress intensity factor (DSIF) at the tip of crack is given, and the numerical examples are provided to show the influences of the parameter combinations of different media upon DSIF.
