Abstract：The three-point bending and in-plane compression of the high strength steel corrugated core sandwich structure was simulated by using the finite element software—ABAQUS. The calculated results were compared to the experimental values and the theoretical values. Then the responses of the sandwich structure under different core materials (high strength steel and carbon steel) and different direction were analyzed. The results showed that the bending strength of the corrugated core sandwich structure of DP900 high strength steel was 2.39 times than that of DC01 low carbon steel. And the compression strength was 1.40 times than that of DC01 low carbon steel. The bending stiffness of the structure in the machine direction was 11.63 times than that in the cross- machine direction.
