An analytical method for the elasto/visco-plastic dynamic problems of axisymmetrical thin shells subjected to mechanical and/or thermal loads is developed. The equations of motion and the relations between the strains and displacements are derived by extending Sanders' elastic shell theory. For the constitutive relations, the Perzyna elasto/visco-plastic equations including the temperature effect are employed. The fundamental equations derived are numerically solved by the finite difference method. As numerical examples, the simply supported cylindrical shells made of mild steel are treated and the following to cases are analyzed ; a nonuniform temperature cylinder subjected to impulsive internal pressure, and an internal pressure cylinder subjected to impulsive thermal load. In both cases the variations of displacements and internal forces with time are discussed.
