Crack Perpendicular to and terminating at a bi-material interface

Wang, Tzuchiang and Stahle, Per LU (1998) In Acta Mechanica Sinica/Lixue Xuebao 14(1). p.27-36
Abstract

By using dislocation simulation approach, the basic equation was formulated. A novel expansion method was proposed for solving the problem. The complete solution to the problem, including the explicit formulae for the T stresses ahead of the crack tip and the stress intensity factors were presented. The stress field characteristics were analysed in detail. It is found that the normal stresses ahead of the crack tip, are characterized by Q field if the crack is within a stiff material and the parameters pt and qt are very small, where Q is a generalized stress intensity factor for a crack normal to and terminating at the interface. If the crack is within a weak material, the normal stresses are dominated by the Q field plus T stress.
