Yerzley mechanical oscillograph test. Method for determining the dynamic mechanical properties of rubber. (ASTM D-945). Results of test are reported as deformation energy, effective dynamic modulus and Yerzley resilience.

Yerzley机械示波器测试。橡胶动态机械性能的测定方法。(ASTM D - 945)。试验结果表示为变形能、有效动态模量和Yerzley回弹。


Yerzley resilience. Measure of resilience of rubber subjected to dynamic loading.

Yerzley回弹性。测定橡胶在动态负荷作用下的回弹性。


Yield point. Stress at which strain increases without accompanying increase in stress. Only a few materials (notably steel) have a yield point and generally only under tension loading.

屈服点。不增加应力的情况下,应变增加时所产生的应力。仅少数材料(特别是钢)


Yield point elongation. Strain at yield point of a material. It is an indication of ductility.

屈服点延伸。材料屈服点的应变。这是延展性的标志。


Yield strength. 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 elastic limit.

屈服强度。是指材料在不引起塑性变形的情况下所能产生的最大应力。它是材料呈现指定永久变形的应力,是弹性极限的一种实际近似值。


Offset yield strength is determined from a stress-strain diagram. It is the stress corresponding to the intersection of the stress-strain curve and a line parallel to its straight line portion offset by a specified strain. Offset is usually specified as 0.2 %, i.e., the intersection of the offset line and the 0-stress axis is at 0.2 % strain.

由应力应变图确定的残余变形屈服强度。它是由应力应变曲线和一条平行于其直线部分的线的交点所对应的应力,这条线由指定应变偏移。偏移量通常指定为0.2%,即偏移线与0-应力轴的交点处于0.2%的应变下。


Yield strength elongation. Strain corresponding to yield strength of material. It is an indication of ductility.

屈服强度伸长率。对应材料屈服强度的应变。这是延展性的标志。


Yield value. Stress in an adhesive joint at which a marked increase in deformation occurs without an increase in load.

屈服值。在不增加负荷的情况下,粘合接头中的应力会发生显著变形。


Young’s modulus. Alternate term for modulus of elasticity in tension or compression. Reprinted from MATERIALS ENGINEERING, June 1967 issue, Reinhold Publishing Corporation, 430 Park Avenue, New York, N. Y. 10022

杨氏模量。又称为拉伸弹性模量或压缩弹性模量。转载自《材料工程》,1967年6月号,Reinhold Publishing Corporation出版,纽约,公园大道430,邮编10022。
