| Abstract: | Dynamic response of the clamped sandwich plate impacted by cellular metallic projectile was investigated using experimental and finite element methods.Effects of the projectile impulse,the faceplate thickness,the thickness of core player and different core layers on the shock resistance performance of structure were discussed.The results indicate that the permanent deformation of the back faceplate is effectively controlled to improve the shock resistance capability of sandwich plate by increasing the thick... |
