DYNAMIC RESPONSE OF ALUMINUM HONEYCOMB SANDWICHPLATE UNDER LOW SPEED IMPACT

Abstract

Abstract: In order to study the dynamic response of aluminum honeycomb sandwich plate under low speed impact, the damage deformation of low speed impact aluminum honeycomb sandwich plate with hemispheric head cylinder was analyzed by finite element simulation software ANSYS/LS-DYNA. The fine simulation model of aluminum honeycomb sandwich plate with face sheet, honeycomb core and cohesive layer was established. The accuracy of the model was verified by comparison with the test results in the literature. The impact response of aluminum honeycomb core unit size and height as well as metal and carbon fiber reinforced composite (CFRP) were studied. The results show that the sandwich plate of larger size of aluminum honeycomb core unit has lower stiffness and stability. The core height has little effect on energy absorption. The influence of cohesive layer on energy absorption cannot be neglected. The energy absorption performance of aluminum honeycomb sandwich panel with CFRP face sheet is better than that of aluminum face sheet.
