The metal corrugated core sandwich panels with superior mechanical performance can be used as crashworthiness and protective structures. Take the V-type corrugated core sandwich panel for example; Analysis of the deformation mode and curves of crushing force versus displacement are made by quasi-static crushing experiment. At the same time, the lateral crushing mechanical behavior and performance of energy absorption is taken with the finite element software Abaqus. The parameters of crushing force, deformation mode, energy absorption and mean crushing strength are compared. The results show that the crushing performance obtained from the experiment is consistent with that from numerical simulation. The deformation mode of the sandwich core structures has great effect on the crushing performance. The specific energy and mean crushing strength of mode I is better than that of mode II.
