Dynamic Response of Aluminum Honeycomb Sandwich Plate Subjected to Impact by Flying Spear
School of Mechanical Engineering, Nanjing University of Science and Technology, 210094 Nanjing, China
Numerical simulation and experiment were applied to study the dynamic response of aluminum honeycomb sandwich plate subjected to the impact by flying spear as well as the the proper velocity of the flying spear impacting on the plate. The deformation mode and damage form of the aluminum honeycomb sandwich plate were obtained. Moreover, the proper velocity of the flying spear is around 40m/s~50m/s. It is confirmed that The deformation area of the upper and lower panels decreases with the increase of the impact velocity, whereas the buckling angle of the panel increases with the increase of the impact velocity. The damage forms of the aluminum honeycomb cell are collapse and buckling sequentially from the impact point to the surrounding. In addition, The collapse area of the honeycomb cells increases with the increase of the maximum diameter of the flying spear and the range of buckling decreases with the increase of impact velocity. The experimental results are in good agreement with the simulation results.
