Abstract
AbstractIn this study, an effort has been made to investigate the mechanical behavior including the fracture toughness of AA5083 aluminum alloy under different loading rates. EDX-spectroscopy is performed to evaluate the chemical composition of the aluminum alloy AA5083. The quasi-static tensile and compressive experiments are performed on a universal testing machine. The quasi-static three-point bend experiments are performed using the MTS-810 machine to obtain the static fracture toughness of AA5083 aluminum alloy. The quasi-static tensile tests and compression tests are performed at different strain rates (10−4 to 10−1/s) and flow stresses have been obtained for the corresponding strain rates. It is found that the aluminum alloy shows strain rate sensitivity in both tension and compression; however, this sensitivity was relatively more dominant in tension than in compression.KeywordsAA5083SpectroscopyStatic fracture toughnessFlow stress and strain rate sensitivity
