Proportionality limit in stress strain curve
Webb8 mars 2024 · Many materials exhibit a proportional relationship between stress and strain up to certain point, referred to as the proportional limit, shown here as point “A.” This stress-strain relationship is known as Hooke’s Law, and in this region, the slope of the stress-strain curve is referred to as the modulus of elasticity (aka Young’s ...
