Dynamic Effects on the Lightweight Design of Metallic Core Sandwich Columns

초록

This study investigated the dynamic effects on the quasi-static optimal solution of metallic sandwich columns, specifically corrugated core sandwich columns made of Al6061T6. To this end, quasi-static lightweight design and the corresponding failure map were given by means of na?e optimization [1,2] and analytical equations [3,4], respectively. And then, dynamic FE simulations were performed for sixteen design points on the failure map in order to examine the failure modes under dynamic compressive loading, V
