T-effect for the interaction problem of an interface macrocrack with a near-tip microvoid

The paper deals with the analysis of the T-effect in the problem of an inte rface macrocrack interacting with a microvoid in the process zone of the ma in crack tip. With the aid of the 'pseudo-traction-edge-dislocation' method . the interaction problem with the T-effect under the remote held loading c onditions can be reduced to singular Fredholm integral equations with Hilbe rt kernel. After solving the singular integral equations numerically, the T -effect on the main crack tip parameters is analyzed and the numerical resu lts are given in figures.
