WebStress Strain Curve . Proportional limit is the point on a stress-strain curve at which it begins to deviate from the straight-line relationship between stress and strain. See accompanying figure at (1 & 2). Elastic limit is the maximum stress to which a specimen may be subjected and still return to its original length upon release of the load. WebStress means force that is applied per unit area. It is generally represented by σ (Sigma) and written as, Fig. 2 What is stress definition formula equation. σ = Forced / Area. σ=F/A. Where, σ = Stress due to application of force. F = The value of applied force to the body. A = The area where the force is applied. twistcutWebAt temperatures above 550°C, these stress values apply only when the carbon is 0.04% or higher on heat analysis. G21.
