In Wikipedia, yield point is stated as follows: A yield strength or yield point is the material property defined as the stress at which a material begins to deform plastically. Prior to the yield point …

Oct 23, 2019 · Also, is yield point and elastic limit two different points or the same? They are synonyms in most contexts. Especially in simple engineering curves like this, yield is the point …

Mar 11, 2023 · Why doesn't the necking start after the yield point but starts from the point of maximum tensile stress in a stress strain curve? Volume being constant during elongation, the …

Hard steels and non-ferrous metals do not have defined yield limit, therefore a stress, corresponding to a definite deformation (0.1% or 0.2%) is commonly used instead of yield limit. …

Apr 21, 2020 · $\begingroup$ I appreciate the equations as well as reference to a model, which I will look more into. One thing I notice, is that these equations imply that upon reaching the …

Jul 4, 2017 · Yield point is essentially the same, except that it is usually defined when the permanent strain reaches a particular level such as 0.2%. Neither the elastic limit nor the yield …

Oct 9, 2018 · Based on the von Mises yield criterion, a material begins to yield at a point when the state of stress at that point is such that the scalar known as the von Mises stress, exceeds the …

Oct 29, 2017 · The von Mises yield criterion is so common, it's often taken for granted. In school book examples, the Tresca yield criterion is also often use (similar, but quite impractical). This …

Dec 9, 2015 · Beyond the proportionality limit, by definition the force and extension are no longer proportional and so Hooke's law is not entirely valid. However, the elastic behaviour itself, …

Aug 1, 2022 · You can also think of yield strength as the end of the elastic region. For ceramics this is convenient because they do indeed have an elastic region. Alternatively, instead of …
