This study is a part of ongoing research to develop lightweight materials that can sustain severe loading conditions. The Split Hopkinson Pressure Bar (SHPB) method will be used for high strain rate tests and the INSTRON tensile testing machine will be used for medium to low strain rate tests. Stress-strain behaviour will be obtained for the different metals under strain rates in the range of 10-3/s to104/s.

This study is a part of ongoing research to develop lightweight materials that can sustain severe loading conditions. The main characteristic of such materials is their ability to withstand large strains under both dynamic compressive and tensile loadings without undergoing fracture. The energy absorption of the material is the governing criteria for this phenomenon. Two different test setups will be used. The Split Hopkinson Pressure Bar (SHPB) method will be used for high strain rate tests and the INSTRON tensile testing machine will be used for medium to low strain rate tests. Stress-strain behaviour will be obtained for the different metals under strain rates in the range of 10-3/s to104/s. One of the objectives of the project is to develop a constitutive material model to predict high strain rate behavior of amour grade steel alloy in high strain rate regime.
