THE INTERFACE CRACK PROBLEM OF THE BI-MATERIAL ELASTIC BODY

In the paper, the stress singularhy and stress intensity factors of bimaterial clastic body with a semi-infinite plane crack in the interface of two materials are considered. Using the general solutions of displacement field in elasticity and the kontorovitch-lebedev integral transformation, we have obtained the exact forms of the stress sigularhy and intensity factors at the crack tip when a pair of symmetric normal concentrated forces are applied on the surface of the crack.
