Abstract Details

2010, Master of Sciences (Engineering), Case Western Reserve University, EMC - Mechanical Engineering.
High Strength Low Alloy steel, grade 65 (HSLA-65) plates used by the US Navy for ship building are to be joined by Friction Stir Welding (FSW) which subjects the work-piece material to high strain rates at high temperatures. The strength of materials varies with the strain-rate and temperature to which they are subjected. Development of constitutive models to get the optimum FSW weld parameters requires experimental determination of the dynamic behaviour of a material at different strain-rates and temperatures. In the current study, experiments using the Split Hopkinson Pressure Bar (SHPB) were conducted on HSLA-65 at high temperatures to generate the true stress-strain curves in compression. In addition, two other materials, which are used in practical applications where high strain rate loading occurs at high temperatures, namely Inconel-718 superalloy (precipitation hardened and annealed) and Aluminum alloy 7075-T6 were also tested using the SHPB.
