The tensile modulus approximately equal to the compressive modulus of elasticity within the proportionallimit.
拉伸载荷模量约等于比例极限内的弹性模量。

In the theoreitical analysis, the effective modulus E was used for the stresses which exceed the proportionallimit.
当应力超过比例极限后，采用了有效模量值。
3
The low proportionallimit may be explained by localized plastic deformation under low macroscopic stress caused by stress concentrations at the ends of SiC whiskers.
