Plastic response of a circular cylindrical shell to dynamic loadings

The dynamic plastic behaviour of a circular cylindrical shell subjected to an initial impulsive loading is studied. It is assumed that the thin walled tube is clamped at the left end and simply supported at the right-hand end. The behaviour of the rigid, perfectly plastic material is controlled by a cubic yield condition which retains the axial bending moment, circumferential membrane force as well as the transverse shear force. Theoretical predictions are presented for a wide range of geometrical and material parameters of the shell.
