[最も人気のある！] yield point stress strain curve 330665-Shear yield strength stress strain curve
The stressstrain curve and a straight line with slope of E and beginning at 0002 (02%) on the strain axis The most satisfactory definition of yield strength for aluminum alloys and many other materials Note At this definition of yield, the plastic portion of the strain is 0002 and the elastic portion of the strain is σ y σ σ y E E 1 1 0 0002 ε εIn materials science and engineering, the yield point is the point on a stressstrain curve that indicates the limit of elastic behavior and the beginning of plastic behavior Below the yield point, a 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 permanent and nonreversible and is known as plastic deformation The yield strength or yield stress is a material propYield strength is a property often used to describe the stress at which the material begins to function in a plastic manner In the figure, the yield strength ...
