Elastoplastic response of cylindrical shells under axial impact

The development of research of inelastic dynamic buckling of cylindrical shells under axial impact is reviewed simply. The Karman-Donnell kinetic equation is used to study the problem of the axiasymmetric ekasto-plastic dynamic buckling of cylildrical shells under fluid-Solid impact. The constitution of material utilizes the increment theory and the increment numerical method is used to solve the kinetic equations. The effect of boundary conditions and radial pressure on the dynamic buckling of cylindrical shells is investigated.
