A review on the mechanical behaviour of aluminium matrix composites under high strain rate loading

AMCs (aluminium matrix composites) are commonly utilized in various structural applications as they possess high strength, low weight, and improved wear resistance properties in comparison to monolithic aluminium alloys. The properties of AMCs generally improve by adding reinforcements. These reinforcements can be ceramics like Alumina, Silicon carbide, or inorganic materials like fly ash. It was noticed that AMCs behave differently with a change in strain rate. Additionally, failure mechanisms under dynamic loading settings are discovered to be distinct from those under quasistatic or low strain rate loading conditions. The wide applications of AMCs rely both on their low strain rate behaviour and high strain rate characteristics. The emphasis of this study is to review the dynamic behaviour of AMCs where the strain rate varies from 100-10,000 s^-1. AMCs were discovered to be strain rate sensitive at increasing strain rates, where their strength and failure strain increases with the strain rate.
