Deformation (engineering)
Videos
In engineering, deformation is the change in size or shape of an object when subjected to force, and may be elastic or plastic depending on whether the deformation is reversible when the actuating for
Considere Plot. (a) True stress-strain curve without tangents. There is neither necking nor drawing. (b) With one tangent. There is only necking. (c) With two tangents. There are both necking and drawing.
Yield (engineering)

In materials science and engineering, the yield point is the point on a stress–strain curve that indicates the limit of elastic behavior and the beginning of plastic behavior. Below the yield point, a

…are caused by mechanical stress, see stress-strain curve. The relationship between stress and strain is generally linear and reversible up until the yield point and the deformation is elastic. Elasticity in materials occurs when applied stress does not surpass the energy required to break molecular bonds…
