This paper presents a finite element method for large deflection elastic-plastic analysis of shells of revolution. The piecewise linear procedure is employed and nonlinearity can be dealt with as the accumulation of linear analyses of numerous loading steps. As for the incremental stress-strain relation in the plastic range, Reuss' equation is used. Especially, a trial of method of treating snap-through buckling is proposed. Some numerical examples are given in order to demonstrate the validity of the present method, and the results are generally satisfactory.
