| Abstract: | This paper evaluates a compact formula incorporating both the Bilby-Cottrell-Swinden (BCS) and the Taira-Tanaka-Nakai (TTN) by considering a rectilinear crack traversing an arbitrary number of zones with different friction stresses. Symmetry is not required. The expressions for the dislocation density and the plastic displacement as well as the stress distribution in the plane of the crack are obtained. |
