Abstract

Axial crush can provide controlled and reliable energy absorption for components requiring structural crashworthiness. An experimental investigation using thin-walled, commercial 304 stainless steel box components examined the effect of alloy composition and microstructure on quasi-static (room temperature) axial crush response. The experimental program consisted of two phases. The objective of the first phase was to develop experimental methods that would generate reproducible axial crush response for a given material. End constraints (removable, grooved caps) and collapse initiators (shallow groove patterns on specimen sidewalls) were used to ensur
