Yield strength is the stress required to produce a smallspecified amount of plastic deformation The yield strength obtained by an offset method is commonly used for engineering purposes because it avoids the practical difficulties of measuring the elastic limit or proportional limitThe minimum yield strength is the key property of steel used in pipeline design See Figure 1110This figure shows the relationship between stress and strain The minimum yield strength is defined as the tensile stress required to produce a total elongation of 05%The magnitude of the stress at which the transition from elastic to plastic occurs is known as the yield strength 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 stressstrain graph of different materials are given below The yield strength of steel and various metals are given in the table below Physics Ultimate Tensile Strength Handwik...
