An analytical method of the elasto/visco-plastic problems of general, moderately thick shells of revolution subjected to asymmetrical loads is developed in consideration of the effect of shear deformations. The elasto/visco-plastic equations of Perzyna are employed for the constitutive relation. The fundamental equations of the elasto/visco-plastic problems derived for incremental values are numerically solved by a finite difference method, and the solutions are obtained by integration of the incremental valued. As a numerical example, the elasto/visco-plastic deformation of a cylindrical shell under locally distributed loads is analyzed, and the results are compared with those from classical theory which neglects the effect of shear deformations. It is shown from the comparison that in the elasto/visco-plastic problem of moderately thick shells, the difference between solutions from present theory and those from classical theory becomes significant.
