摘要：
The dynamic response of sandwich plates with identical face sheets separated by compressible PVC (polyvinyl chloride) core subjected to shock loading was investigated. Combined with the three-dimensional digital image correlation technology, the deflection-time history of the back face sheet was measured. Deformation and failure modes of the sheets and core were exhibited to examine the effects of the projectile impulse and the core density. It was found that the fracture and failure occurred mainly at the center of the sandwich plates, and the deflection of the back sheets decreased gradually from the center to the outside, and finally the deformation turned into a corn-like shape. The results indicate that there is a good linear relationship between the projectile impulse and the permanent deflection of the central point of the back face sheets. Reducing the density of the core and raising the thickness of the core can effectively decrease the deflection of the back face sheets while maintaining the quality. The experimental results can provide help for the optimum design of polymer sandwich structures. © 2017, Editorial Board of EXPLOSION AND SHOCK WAVES. All right reserved.
