Investigation of the penetration behavior of alsi7 foam, produced by powder metallurgy method, under low-velocity impact energies

Abstract

In this study, the impact behaviors of AlSi7 foams under low-velocity impact energies were investigated. The low-velocity impacts (1,2 -3 ms(-1)) were applied to the samples with 55x55x20 mm dimensions using the weight drop test machine. The impact tests were performed until perforation took place on a sample and so penetration and perforation impact behavior were analyzed. The changes in the internal structures of the samples after the impact were observed in the macro level.
