Description
Summary:In this paper, a sinusoidal honeycomb sandwich panel structure with negative Poisson’s ratio is studied. The impact dynamic response of sandwich panel with two kinds of in-plane and out-of-plane with sinusoidal honeycomb structure with the same relative density and different amplitudes at different impact speeds was studied based on ANSYS finite-element software. At different speeds, the sandwich panel impact process is divided into three stages, (a) partial perforation, (b) impact limit, and (c) full perforation. In the stages (a) and (b), the sinusoidal honeycomb is superior to the conventional honeycomb sandwich panel. When reaching the stage (c), the impact reaches the limit, the amplitude increases but the energy decreases, and the energy is almost unchanged when the speed is changed. The results show that the impact resistance of the sinusoidal honeycomb structure is directly related to its amplitude and impact velocity, compared with the conventional quadrangular honeycomb structure, the negative Poisson’s ratio effect of the sinusoidal honeycomb structure can improve the energy absorption capacity of the panel and have better impact resistance, which provides a reference for the design of improving the impact resistance of the structure.
