Abstract

The theoretical analyses developed in chapter 1 have examined the influence of inertia on the response of an elementary structure subjected to dynamic loads which cause plastic behaviour. The yield criterion, which governs the plastic flow, was assumed to be independent of the rate of strain (\(\dot \varepsilon \)). However, the plastic flow of some materials is sensitive to strain rate, which is known as material strain rate sensitivity, or viscoplasticity [3.1]. This phenomenon is illustrated in Figure 3.1 for mild steel specimens which were tested at various uniaxial compressive strain rates [3.2].
