INTRODUCTIONGreat attention has been paid in recent years to the investigations of dynamic growth of cracks in elastic solids under mixed mode loading conditions due to the practical importance. A crack usually propagates along a curved path under mixed mode loading. Freund and Clifton showed that the near-tip singular stress field for growing cracks has universal spatial dependence in a local Cartesian coordinate system(x, y)centered at the moving crack tip in such a way that the crack tip velocity vector is in展开更多
There are a few analytical solutions of the coupling analysis of creep damage even to simple problems. In this letter, the analytical solutions to deformation of a thick-walled cylinder and spherical shell are deduced.
