WebStress strain curve yield point is the material property defined as the stress at which a material begins to deform plastically. Prior to the yield point the material will deform elastically and will return to its original shape when the applied stress is removed. Once the yield point is passed, some fraction of the deformation will be ... WebSep 2, 2024 · Since it is often difficult to pinpoint the exact stress at which plastic deformation begins, the yield stress is often taken to be the stress needed to induce a specified amount of permanent strain, typically 0.2%.

WebSep 12, 2024 · Stress is a quantity that describes the magnitude of forces that cause deformation. Stress is generally defined as force per unit area. When forces pull on an object and cause its elongation, like the stretching of an elastic band, we call such stress a tensile stress. When forces cause a compression of an object, we call it a compressive … WebApr 11, 2024 · The yield strength is defined as the stress that will induce a specified permanent set, usually 0.05 to 0.3 percent, which is equivalent to a strain of 0. 0005 to 0.003. The yield strength is particularly useful for materials with no yield point. 屈服强度被定义为产生某一特定永久变形的应力，其永久变形通常为0.05% ~0. ...

WebAug 10, 2024 · On the stress-strain curve, this area is called the Hooke’s region. The reason lies with the applicability of Hooke’s Law for forces that fall into the area. Yield Limit. As soon as the specimen passes the proportional limit, it enters the yield limit region. At this point, permanent deformation sets in.
