Abatrac-Based upon the results of previous work [K. M. Lin et al., Muter. Sci. Engng 95, 167 (1987)], the system of a screw dislocation dipole interacting with an internal crack is studied. The analytic formulae of the physical variables, such as stress field, strain energy and thpping energy, image

Screw dislocations near a crack penetrating through an interface were investigated. Based on the solution of homogeneous solid, we derived the stress field, stress intensity factors and crack extension forces at both crack tips, and the image force and strain energy of screw dislocations. The mechan

The interaction between screw dislocations and an interfacial blunt crack and a sharp crack under loads at infinity is dealt with. Utilizing the Muskhelishvili complex variable method, the closed form solutions are derived. The stress intensity factor and critical stress intensity factor for disloca
