An exact solution to an elastic-plastic stress-concentration problem: PMM vol. 35, n≗1, 1971, pp. 40–48

An exact elastic-plastic solution is found for the stresses around a circular hole in a sheet subjected to balanced biaxial tension at infinity. The sheet is orthotropic, but isotropic in its plane. The solution, based on a J 2 type of deformation theory together with a modified Ramberg-Osgood law, is rigorously valid for flow theory as well.
