Abstract

Abstract Multi-cell columns inspired by diatom algae have been examined regarding crashworthiness. Crushing simulations have been conducted for AA2024-T351, B1500HS-O25, and a combination of these materials. The highest specific energy absorption and lowest peak crushing force value were obtained with a homogenous AA2024-T351 column. Single and multi-objective optimization studies have been conducted with this column to find the best design. This design could be used in crash-box-like structures in automotive design.
