Abstract
Thin-walled energy absorbers are used to reduce accident induced damages. In this study, thin-walled stainless steel structures in quasi-hemisphere geometry were subjected under quasi-static loading with Santam 150KN apparatus. Experimental results were compared with results of numerical simulations by LS-DYNA and it was shown that there is a good agreement between experimental and numerical results. Also, the multi-cell quasi-hemisphere specimens were numerically investigated and it was presented that increasing the number of cells increases the absorbed energy. The results showed that Six-cell specimen with the largest diameter and the minimum thickness has the most increase of Specific Absorbed Energy (SAE).
