| Abstract: | A new kind of rectangular honeycomb sandwich stiffened cylindrical shell was proposed.The responses and shock-protection mechanism of this new structure were analyzed.Here,the commercial code LS-DYNA was employed to analyze the dynamic responses of this new sandwich structure subjected to underwater explosion shock load.The largest deformation and plastic strain of thepressured hull were selected as the indicators to evaluate the effects of typical parameters on the anti-shock performance of the structure.A... |
