Question

We've been given then stress-strain data of 3 materials pulled to failure: Low Carbon Steel, 7075 T6 Al, and PMMA. We were given initial lengths of the material:

Material Initial Gauge Length (m) Final Guage Length (m) Original Thickness (m) Final Thickness (m) Original Width (m) Final Width (m) Low C 1020 Steel 0.1528 (6.015 in)* 0.1828 (7.197 in)* 0.003 (0.119 in) 0.00127 (0.05 in) 0.0125 (0.492 in) 0.0077 (0.305 in) 7075-T6 Al PMMA 0.0508 0.0574 0.00615 0.00569 0.01295 0.01229 0.254* 0.259* 0.00586 0.00502 0.01283 0.01222

With the stress-strain data, our first task was to creak stress-strain curves which I did in excel.

Low Carbon Steel:

7075 T6 Al:

PMMA:

Please help me find yield strength, ultimate strength, modulus of elasticity, resilience, the percentage of elongation, and curve type.
