Abstract
A theoretical and experimental study of the elastic-plastic response of certain structures to impact and impulsive load is described. Lead rings were allowed to fall freely on to a flat and pointed sharp anvil, aluminium rings were subjected to the impact of a free falling sharp indenter and thin aluminium cantilevers, rectangular and triangular frames and semicircular arches were subjected to magnetomotive and explosive impulse.A numerical solution based on a finite difference approximation was developed to describe the response of an equivalent lumped parameter model for each of the above structures. This method, although restricted to two-dimensional structures, can be applied to a variety of structural elements.High-speed photographs were taken for each of the loading events and the experimental data obtained were compared with the theoretical plastic response predicted by the numerical method.
