Further experimental investigations on the failure of clamped beams under impact loads

Abstract Experimental results on the deformation and failure of clamped beams, made from aluminium alloy or mild steel and struck by a mass, are reported in this paper. Complete engineering and true stress-strain curves at strain rates up to 140 s -1 are presented for the materials. In addition, the dependence of rupture strain on strain rate is explored. These results provide experimental information of value for further numerical and theoretical studies on the dynamic inelastic failure of structures.
