HIGH STRAIN RATE BEHAVIOUR OF ALUMINIUM ALLOYS USING SPLIT HOPKINSON BAR (SHB) TESTING

摘要

In certain engineering materials processes (e.g. machining) the material is required to operate in high temperature conditions where at the same time deformation occurs in a very small period of time. In such cases the material's mechanical behaviour can differ significantly from the behaviour obtained by conventional quasi – static tension or compression tests. Hence, experimental data is required that can describe the material's behaviour under high strain rate (SR) and high temperature conditions.
