Stress–strain Curve - Wikipedia
Ductile materials, which includes structural steel and many alloys of other metals, are characterized by their ability to yield at normal temperatures.. Low carbon steel generally exhibits a very linear stress–strain relationship up to a well defined yield point (Fig.2).The linear portion of the curve is the elastic region and the slope is the modulus of elasticity or Young's Modulus. ...
