摘要：
The structural responses under the impact loading of air explosion of corrugated sandwich panels were analyzed, and the method for forecasting plastic deformations was proposed. The maximum plastic deformations of two typical corrugated sandwich panels under impact loading were analysed both theoretically and numerically. The results are in good agreement with each other, and the reliability of the theoretical analysis method was thus verified. On this basis, in order to further test and improve the analytical calculation method, a typical section of the corrugated sandwich panels was selected, and the similarities and differences of deformation modes between the theoretical analytical method and the numerical simulation method were analyzed. The results provide a reference to the parametric design and impact resistance evaluation of corrugated sandwich panels. © 2019, Editorial Office of Journal of Vibration and Shock.
