ABSTRACT
Abstract This paper contains a summary of the results which have been obtained from experimental scaling tests on structures subjected to dynamic loads producing large inelastic deformations. Three independent studies show significant and similar departures from the laws of geometrically similar scaling, while another study on the perforation of plates at low impact velocities shows that the laws are satisfied, at least within the accuracy expected in such tests. Some observations are offered on these experimental results and on several aspects of the required scaling laws for the dynamic inelastic response of structures with material failure. Keywords: Inelastic impact, geometrically similar scaling, dynamic experiments, perforation, rupture, structures.
