Abstract
Using the pseudo-equilibrium hybrid element, we formulate the equation of motion which the structures are subjected to the plastic large deformation. And the dynamic responses of cylindrical shell, which is simply supported at both ends and compressed in the direction of its axis, are examined. In this study it is restricted us to consider an axisymmetrical deformation. As a result, it is recognized that the amplitude of prescribed load and the deformation velocity cause the apparent differences of deformation modes compared with the static one.
