    Yield strength is defined in engineering as the amount of stress (Yield point) that a material can undergo before moving from elastic deformation into plastic deformation. Most steels have an endurance or fatigue limit about half the Tensile Strength.

  17. Tensile Strength vs Yield Strength - Clifton Steel

    Yield Strength. Yield strength is the maximum stress that can be applied before it begins to change shape permanently. This is an approximation of the elastic limit of the steel. If stress is added to the metal but does not reach the yield point, it will return to its original shape after the stress is removed.
