Abstract

Journal of Sandwich Structures & Materials, Ahead of Print.
To explore interface effects between the soft and hard layers of cellular solids, the shock wave propagation of the functionally graded cellular sacrificial layers (FGCSLs) under impact load was investigated in this paper. Firstly, a theoretical model of ...
