【Abstract】

<正>Due to the two adjoining cylindrical shells existing,deformation mode of multirow cylindrical shells structure under radial dynamic pressure was not the four-plastic -hinge framework.On the base of mechanics analysis,quasi-static experiment,small explosion experiment and numerical simulation,the plastic deformation behavior of multi-row cylindrical shells is clear and the number of plastic hinges is eight.The eight-plastic-hinge framework consists of four moving hinges, which the edges of plastic zone move ceaselessly outward,and four fixed hinges, which the comparative size of plastic zone is changeless.Moreover,the movement field is described and the place of plastic hinges is established.In view of the dynamic strain rate and strain hardening of material,the expressions of the plastic bending moments nearby the plastic hinges are presented.
