Recently, Dr. Zhang Zhijia published entitled "Free vibration analysis of sandwich beams with honeycomb-corrugation hybrid cores" in the capacity of first author of the Composite Structures, which is under the guidance of Han Bin lecturer, Professor Zhang Qiancheng associate professor and Professor Jin Feng.

In this paper, the equivalent equivalent of the corrugated-honeycomb composite core is used, and the macroscopic equivalent constants of the composite core in the small deformation range are obtained. The equivalent model of the corrugated-honeycomb composite core is applied to the ripple-honeycomb In the free vibration analysis of composite core sandwich structure, the results are in good agreement with the results of modal experiment and finite element calculation. The model greatly simplifies the calculation time and cost. In this paper, the researchers in the practical application of the design of cellular - corrugated composite sandwich structure has a good guiding significance
