Quantification of impact energy dissipation capacity in metallic thin-walled hollow sphere foams using high speed photography

Abstract:

Quantification of energy dissipation capacity in metallic foams is required for their application in transport components subject to high velocity impact loads. In this study, in-situ high speed photography combined with in-house grid tracking codes was used to quantitatively investigate the impact behavior of electrodeposited nickel thin-walled hollow sphere foams in gas gun impact testing at an initial velocity of 60-140 m s-1. The energy dissipated by the foam varied almost linearly with t...
