Look at only curve for 18-8 SS
a) engineering yeild stress is a .2% offset from the linear elastic slope to the curve of the line - draw line over to coresponding stress. Defines when material goes from elastic (linear) to plastic (curved) deformation; ˜ 120 psi
b) Tensile Strength (UTS) is the highest point on the graph ˜ 180 psi
c) strain at fracture ˜ .12 in/in
d) E = slope of linear/elastic portion of line ˜ 12 x 103 psi
