WebJan 2, 2024 · Add a comment. -1. As has been mentioned in other answers, the Young's modulus, E, is the ratio of stress to strain in the elastic range of stress/strain curve and is a constant, not a derivative. It is a constant as opposed to what a derivative implies which is a variable depending on the local curvature. WebSpecifically, the yield point is where the stress-strain curve has a 0.2% offset from the Young’s modulus. Engineers use this 0.2% offset to have an easily-identifiable point on the stress-strain curve. Technically what I’ve been describing so far is called the “proportionality limit” which is the exact point that stress and strain are ... iowa hawkeyes vs illinois scoreWebThis is because stress is proportional to strain. The gradient of the straight-line graph is the Young's modulus, E. E is constant and does not change for a given material. It in fact represents 'stiffness' property of the material.
