Introduction To Yield Strength Of Materials

Yield strength of materials introduction 1, yield point, steel or specimen in tension, when the stress exceeds the elastic limit, timely stress is not increased, but steel or specimen still continue to occur obvious plastic deformation, this phenomenon is called yield, and the minimum stress at which the yield occurs is called the yield point. 2, yield strength, some metal materials yield point is not obvious, it is difficult to measure, so in order to measure the yield characteristics of the material, the requirements produce permanent residual plastic deformation equal to a certain value of the stress, it's called conditional yield strength. 3. Tensile strength, the maximum stress that a material reaches from the beginning of the tensile process to the point of fracture. It indicates the size of steel resistance to fracture, and tensile strength corresponding to the compressive strength, bending strength and so on. 4. Elongation, the ratio of the plastic elongation of a material to that of the original specimen after breaking. 5, yield ratio, steel yield point and tensile strength ratio, called yield ratio. The greater the yield ratio is, the higher the reliability of structural components is. 6. Hardness is the ability of a material to resist being pressed into its surface by a hard object.
