    Abstract

    Small Punch Tests (SPTs) were conducted in order to determine material properties and understand their mechanical behavior. Equations were derived to calculate the yield strength, ultimate tensile strength, modulus of elasticity, and hardness of five aluminum alloys. A greater understanding of the mechanisms of the SPT and how specimens behave during testing is also discussed. It was found that the 2024-T3 and 7075-T651 aluminum alloys were shown to have the highest maximum small punch force before failure. The relationship between the SPT parameters and the yield strength, tensile strength, elastic modulus, and hardness is shown to be linear. The empirical equation developed here is suitable for aluminum alloys.
