ABSTRACT
In this chapter, the dynamic mechanical responses of single and multilayered aluminium alloy AA5083 were investigated at different strain rates using a split Hopkinson pressure bar. The specimens with circular cross-sections of aspects ratios 1, 0.75, and 0.5 were used during compression experiments at high strain rates. The thin layered soft cotton materials were used as pulse shapers to obtain dynamic equilibrium during experiments. It was seen that the stress-strain behaviour of materials under high strain rate loadings was different than that of low strain rates. The design of multilayered structural components subjected to high strain rate loadings requires dynamic properties of materials. Generally, multilayered stacking used in military armour is subjected to high loading rates during service. Multilayered stacking is also used in compound cylinders and airframes to provide strength in the structures. The true stress-strain diagrams for aluminium alloy AA5083 at different loading rates were evaluated and presented.
