下屈服强度英文

屈服强度σb 抗拉强度σs 延伸率δ 断面收缩φ 抗冲击Ak 这是机械设计手册中介绍的,供你借鉴.

1、屈服强度：“ys”可以表示屈服强度，是英文“yieldstrength”的缩写，屈服强度就是指金属在发生屈服现象时的极限，即抵抗变形的能力。在小于极限值的外力作用下，金属会恢复至原来的状态；当外力作用大于极限值，金属会发生永久变形。2、其他词语缩写：“ys”还可能是其他词语或英文词组的缩写，如：“预售”、“Yugoslavia（南斯拉夫）”、“Yugoslavian（南斯拉夫人）”等等。

抗拉强度 compressive strengthCompressive strength is the capacity of a material or structure to withstand loads tending to reduce size.屈服强度 yield strengthA yield strength of a material is defined in engineering and materials science as the stress at which a material begins to deform plastically.比例极限 proportionality limit Up to this amount of stress, stress is proportional to strain (Hooke's law), so the stress-strain graph is a straight line, and the gradient will be equal to the elastic modulus of the material.弹性极限 elastic limit Beyond the elastic limit, permanent deformation will occur. The elastic limit is therefore the lowest stress at which permanent deformation can be measured. 延伸率 stretch ratioThe stretch ratio or extension ratio is a measure of the extensional or normal strain of a differential line element, which can be defined at either the undeformed configuration or the deformed configuration. 断面收缩率 shrinkage ratioWhen the material tensioning fracture section decreased, the ratio of cross-sectional area reduced to the original area of the section is called shrinkage ratio.
