Taste test machine test -what is the yield strength -qinsun


The mechanical properties of metal reflect the ability of metal materials to resist deformation or destruction under various forms of external forces. Generally, it is necessary to do tensile strength, yield strength, and extension strength, but many purchases do not understand what the yield intensity is? Kunshan? Qinsun instrument as a pull -for -test machine manufacturer is your yield strength?

What is the yield strength? The yield strength is only for elastic materials, and no elastic materials have no yield strength. For example, all kinds of metal materials, plastics, rubber, etc. are elastic and yield strength. And glass, ceramics, masonry, etc. generally do not have elasticity. Even if this material is elastic, it is minimal, so there is no such thing as a yield. The zUI high stress that can bear during the yield phenomenon When the stress exceeds the elastic limit, the deformation increases faster. At this time, in addition to the elastic deformation, some plastic deformation is also produced. Some steel (such as high -carbon steel) does not have obvious yield phenomena, and usually uses the stress of the trace plastic deformation (0.2%) as the yield strength of the steel, which is called the conditional yield strength. The intensity of the point is the yield strength of the material! In terms of the exerted tension, the tensile value of this critical point is called the yield point.
