Design optimization of square aluminium damage columns with crashworthiness criteria

Abstract

This paper studied the deformation and damage behaviors of aluminum-alloy under crushing loadings. The numerical analysis is carried out by Abaqus software. subsequently, the collapse behavior of aluminium extrusion damage was experimentally characterized. Finally in order to find more efficient and lighter crush absorber and achieving minimum peak crushing force, response surface methodology (RSM) has been applied for optimizing the square aluminium extrusion tube.
