- Yield: evidence of plastic deformation
in structural materials. also called plastic flow or creep. see also flow.
- Yield point: the first stress in a material,
usually less than the maximum attainable stress, at which an increase in strain
occurs without an increase in stress.
- Yield strength: the stress at which
a material exhibits a specified deviation from proportionality of stress and
strain. An offset of 0.2% is used for many metals.
- Yield stress: the stress level in a
material at or above the yield strength but below the ultimate strength, i.e.
a stress in the plastic range.
