definition of yield strength
Oct 08, 2013 · Yield strength refers to an indication of maximum stress that can be developed in a material without causing plastic deformation. It is the stress at which a material exhibits a specified permanent deformation and is a practical approximation of the elastic limit. In engineering structural design, yield strength is very important.
Definition of yield strength. :the stress at which a piece under strain is deformed some definite amount (as 0.1 or 0.2 percent) Yield strength definition and meaning Collins English noun. ( Mechanical engineering:Materials) The yield strength of a bar of material is the maximum stress that can be applied along its axis before it begins to change shape. Steel yield strength is the amount of stress a piece of steel must undergo in order to permanently deform.
Yield strength is a constant that represents the maximum limit of elastic behaviour. Ductile materials like metals have higher yield strength values than plastics. The stress-strain graph of different materials are given below. The yield strength of steel and various metals are given in the table below. Material.
