Abstract
This paper studies the dynamic deformation behaviour of aluminium alloys such as 2024-T3 and 6061-T6 by using a modified high-temperature split Hopkinson pressure bar (SHPB) technique with a pulse shaper at elevated and room temperature range. An experimental strategy has been proposed and evaluated with the modified high-temperature SHPB apparatus. The experiments were carried out on two types of aluminium alloys at various strain rates and at temperatures ranging from 25°C to 500°C. The reflected wave with pulse shaper, the true stress – true strain relationship, strain rate, front-end and back-end stress with time scale are described at room and high temperature.
