Test data of rubber material were fitted with hyperelastic constitutive models in ABAQUS finite-strain package. On the basis of the fitting results; a proper model was proposed. Furthermore; dynamic responses of chiral honeycomb rubber claddings subjected to UNDEX were investigated; and the influences of main design parameters including height; porosity and panel material on shock resistance were discussed. It is found that as cladding's height; porosity and panel wave impedance increase; its shock resistance and buffering effect will be improved. The conclusions play an instructive role in understanding the protective mechanism and the performance of chiral honeycomb claddings subjected to underwater explosion; and also provide a guideline to further optimal design;
