be flexible under stress of physical force; "This material doesn't give"

The first stress in a material, less than the maximum rate attainable stress, at which the strain increases at a higher rate than the stress. The point at which permanent deformation of a stressed specimen begins to take place.

Synonym for the plastic deformation of a particulate solid.

Strength--Maximum stress that can be applied without permanent deformation of material.

When an object is bent so far that it does not spring back to its original shape when the stress is removed, it is said to yield.

Evidence of plastic deformation in structural materials. Also called plastic flow or creep. See also flow.

Evidence of plastic deformation in structural materials. Also known as plastic flow or creep.

Yield strength, or the yield point, is defined in engineering and materials science as the stress at which a material begins to plastically deform. 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 permanent and non-reversible.
