The Determination of Stresses in Plastic Regions in Problems of Plane Flow

A simple numerical-graphical method for the calculation of stresses in plastic zones adjacent to boundaries of arbitrary shape is outlined, applicable to problems of plane plastic flow in ideally plastic materials. For illustration, the method is applied to determine the stresses in plastic zones near elliptic free boundaries. The yield load of a tensile bar containing elliptic notches is obtained for a series of notches of varying sharpness. Some related problems are discussed briefly.
