Elastoplastic equilibrium in a disk having an edge crack

Summary The _C model and singular integral equations have been used to solve for the elastoplastic state of stress and strain in a disk containing an edge crack, and the solution has been used to determine crack edge separations, including those at the vertex and at the edge of the disk. The critical loads calculated from the _C model and Irvin's criterion have been compared with measurements.Translated from Fiziko-Khimicheskaya Mekhanika Materialov, Vol. 26, No. 1, pp. 38–46, January–February, 1990.
