A new kind of rectangular honeycomb sandwich stiffened cylindrical shell is proposed. The responses and shock‐protection
mechanism of this new structure are analyzed. In the study, the commercial code LS‐DYNA is employed to analyze the dynamic
responses of this new sandwich structure subjected to underwater explosion shock load. The largest deformation and plastic strain of
pressure hull are selected as the indicators to evaluate the effects of typical parameters on the anti‐shock performance of the structure.
At last, the anti‐shock performance of a typical honeycomb sandwich stiffened cylindrical shell in different shock environment is also
investigated.
