Abstract

A method for calculating the limiting load under plane deformation, when the yield line divides the body into two parts, is proposed. The geometry of the yield line is determined by methods of variational calculus; within the framework of the proposed assumptions. The stress function, which determines the appearance of a straight line (strip) of yield, is obtained.
