Abstract：The behaviours of foamed aluminum-filled prisms were studied under quasi-static loading conditions by LS-DYNA. Column shell ratio (R) is the base to compare foamed aluminum-filled prisms with different cross sections. Energy absorption quantitative analysis and comparison of foamed aluminum-filled prisms was carried out by specific energy absorption, specific force and energy absorption rate. Specific energy absorption of foamed aluminum-filled square prism was highest. Energy absorption rate of foamed aluminum-filled octagonal prism was highest (78%). The share of square pipe in total energy absorption of foamed aluminum-filled square prism is least (57%). Different shape and structure have great influence on foamed aluminum-filled prisms. Meanwhile, the deformation pattern and inherent mechanism of foamed aluminum-filled prisms are analysed.
