摘要：
A Zener-Stroh Curved crack is defined such that the crack undergoes an initial displacement discontinuity. A singular integral equation is suggested to solve the Zener-Stroh curved crack problem. General formulation for evaluating the stress intensity factors and the T-stresses at the crack tips of a Zener-Stroh curved crack is carried out. For the Zener-Stroh arc crack, T-stresses at the crack tips can be evaluated in a closed form. (C) 2008 Elsevier Ltd. All rights reserved.
