Abstract A corrugated sandwich plate was prepared by metal rubber, and the macro and micro mechanical properties of the structure were studied by experiment and finite element respectively. In order to accelerate the calculation rate, the finite element equivalent model was established, and the influence of different material parameters on the mechanical properties of the structure was studied and verified by experiment. The results show that there are two stages under load: platform stage and compact stage. Compared with traditional corrugated sandwich board, the platform stage is longer and the energy absorption effect is improved. Combined with the test and the finite element, it is found that the reason for these two stages is that the ultimate load can cause the buckling deformation of the sandwich layer under the loading condition, thus reducing the internal voidage of the structure, and the structure is further loaded to the dense stage. The validity of the research results is verified by the comparison of the two, which provides guidance for the future design and application of metal rubber corrugated sandwich plate.
