With the help of the equation of optimum overstrain or depth of the plastic zone, a set of concise and accurate equations for residual stresses and their equivalent stress as well as the total stress and their equivalent stresses are obtained, and features of these stresses are discussed, thereupon the law of distribution and the varying tendency of these stresses become clearer. Safe and optimum load-bearing conditions for a cylinder are presented.
