The following shows the stress-strain curve for an aluminum tested in the Instron 3367 equipment from the Materials Laboratory. The complete curve and a curve with its initial detail are presented. From this curve estimate the following characteristics. a. Stress to yield (MPa) at 0.2% deformation offsetb. Maximum strength (MPa)c. Strength (MPa) and deformation (%) in fractured. Elastic modulus (MPa)
