Effect of Manufacturing Processes and Welding Type on Quasi-static and Dynamic Responses of Aluminum Alloys: Experiments and Modeling

Measured responses of two aluminum alloys over a wide range of strain-rates (10−5 to 103 s−1) and temperatures are presented. The aluminum alloys include AA5182-O and AL6111-T4. A tensile spilt Hopkinson pressure bar was used for the dynamic experiments. The aluminum AA5182-O alloy (manufactured using continuous casting and direct chilling processes) including its first and second generation gas tungsten arc welded and friction stir welded TWB’s...
