Elastic Limit, Apparent
Arbitrary approximation of the elastic limit of materials that do not have a significant straight line portion on a Stress/strain diagram. It is equal to the Stress at which the rate of strain is 50% greater than at zero Stress. It is the Stress at the point of tangency between the Stress- Elastic Hysteresis strain curve and the line having a slope, with respect to the Stress axis, 50% greater than the slope of the curve at the origin.
