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 with
   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 2.39times higher than that of
   DC01low carbon steel.And its compression strength was 1.40times higher
   than that of DC01low carbon steel.The bending stiffness of the structure
   in the machine direction was 11.63times higher than that in the
   cross-machine direction.
