A two-dimensional anti-plane shear crack \(\Sigma\) with a finite process zone \(\delta c\) embedded in an elastic body \(A\). The closed curves with arrowheads, \(\Gamma_{{{\text{ex}}}}\), \(\Gamma\) and \(\Gamma_{{\text{c}}}\), represent three different integration paths surrounding the process zone \(\delta c\). The vectors \({\mathbf{T}}\) and \({\mathbf{u}}\) represent the traction and displacement at a point on the integration path \(\Gamma\), respectively
