Abstract A finite element analysis of the blast resistance star-shaped honeycomb (SSH) core sandwich structure was carried out by using CONWEP calculation model, with maximum deformation, energy absorption, and area specific absorption as indicators explosion resistance. Based on method verified experimental data, influence structural parameters each part SSH panel its anti-explosion performance quantitatively investigated. The results show that increase connecting ligament L cell wall angle θ can improve panel; deformation capacity decreases three thickness coefficients (cell t , front f back b ); greater TNT equivalent, panel, dissipation; use panels a protective in protection systems significantly reduces deflection enhances compared to solid equal mass, respectively.
