Dynamic Plastic Instabilities in Nonlinear Inelastic Response to Pulse Loading

Abstract

The report summarizes the main results obtained, with emphasis on the energy approach introduced first for a single degree of freedom model, and then developed for a two degree of freedom beam model. The elastic strain energy function is plotted as a surface over the displacement coordinate plane, whose topography depends on the plastic strains. It provides a guide to the various types of beam response, which may be quasiperiodic or chaotic, and enables their dependence on parameters such as impulse magnitude and damping to be clearly understood.
