英文摘要	The projectile impact resistance of sandwich panels with cellular cores with different layer numbers has been numerically investigated by perpendicular impact of rigid blunt projectile in ABAQUS/Explicit. These panels with corrugation, hexagonal honeycomb and pyramidal truss cores are impacted at velocities between 50 m/s and 202 m/s while the relative density ranges from 0.001 to 0.15 The effects of core configuration and layer number on projectile impact resistance of sandwich panels with cellular cores are studied. At low impact velocity, sandwich panels with cellular cores outperform the corresponding solid ones and non-montonicity between relative density and projectile resistance of sandwich panels is found and analyzed. Multiplying layer can reduce the maximum central deflection of back face sheet of the above three sandwich panels except pyramidal truss ones in high relative density. Hexagonal honeycomb sandwich panel is beneficial to increasing layer numbers in lowering the contact force and prolonging the interaction time. At high impact velocity, though corrugation and honeycomb sandwich panels are inferior to the equal-weighted solid panels, pyramidal truss ones with high relative density outperform the corresponding solid panels. Multiplying layer is not the desirable way to improve high-velocity projectile resistance.; National Natural Science Foundation of China [11302270, 11572059]; Ph.D. Programs Foundation of Ministry of Education of China [20130191120015]; Chongqing Natural Science Foundation [cstc2013jcyjA00030]; State Key Lab for Strength and Vibration of Mechanical Structures of Xian Jiaotong University [SV2015-KF-12]; SCI(E); ARTICLE; clm07@cqu.edu.cn; fangdn@pku.edu.cn; 15; 2576-2595; 13
