TL;DR: In this paper, the authors considered the plane problem of a central crack in a rectangular sheet of orthotropic material and found the solution by an extension of the modified mapping-collocation technique, originally formulated for plane isotropic analysis.

TL;DR: In this article, the authors considered the plane elastic problem corresponding to a radial crack emanating from the internal boundary of a circular ring and derived the stress intensity factors at the crack tip by using the recently derived modified mappingcollocation technique.

TL;DR: In this article, a physically acceptable solution for a central crack in an infinite sheet or a strip in pure bending is compared with the corresponding classical solution, and the classical solution is non-conservative and, for both the strip and the infinite sheet, underestimates the stress intensity factor at the crack tip in the tensile field by approx. 9%.

TL;DR: In this paper, it was shown that the stress intensity factors for the end rotation problem for a cracked-rectangular sheet can be determined from a knowledge of the solution for a uniform normal displacement without rotation.
