Young s Modulus

The longitudinal yield strength and the Young′s modulus increase with the draw ratio.

纵向屈服强度和模量随拉伸比增加而提高。

Based on the theory of Fraunhofer diffraction, an improved method is introduced to measure Young ' s modulus of steel wires using CCD.

根据夫琅和费衍射原理，采用CCD来测量金属丝在拉力作用下的微小伸长量，对钢丝的杨氏模量进行了测量。

As comparing with adopting traditional optical lever method to measure Young 's modulus of elasticity E. Using optical sensor is much better in both operation and data precision.

对杨氏弹性模量E用反射式位移传感器与传统的光杠杆法测量进行比较，得出无论从操作方面还是数据的精确度方面都说明了光纤传感器法大大优于光杠杆法。
