T-stress in the Zener–Stroh arc crack problem in plane elasticity

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.
