| Abstract: | The increment theory and the increment numerical method are used to analyzed the elastic-plastic dynamic buckling of ring-stiffened cylindrical shells under c ombined loading (axial fluid-solid impact loading and radial uniform external pressure). A method based on the B-R criterion and the Southwell method is resp ectively applied to obtain the critical loads. The effects of radial uniform ext ernal pressure on the dynamic buckling characteristics and the load carrying abi lity against axial impact of cylindrical shells are discused. |
| Keywords: | increment theory combined loading r ing stiffened cylindrical shells elastic-plastic dynamic buckling load-carry ing ability against axial impact |
