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.Yield Strength vs.Tensile Strength - What's the In brittle materials,tensile strength is reached with minimal or no yield.Tensile strength is usually of a higher numerical value than the yield strength of a particular material.The tensile strength of a material can be ascertained with 100% accuracy.However,yield strength has to be estimated for most materials.Yield and tensile What is a Fatigue Strength? - Definition from CorrosionpediaNov 22,2013 THE COMPARISON OF YIELD AND FATIGUE STRENGTH#0183;It is common to estimate fatigue strength as some fraction of ultimate tensile strength that is specific to a material type (for example,35% for austenitic stainless steels).Fatigue strength is as important to the design of parts with high deflection cycles,as yield strength is to the designer who must obtain requisite contact forces.
