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。

The low proportionallimit may be explained by localized plastic deformation under low macroscopic stress caused by stress concentrations at the ends of SiC whiskers.
复合材料低的比例极限可由晶须端部应力集中所导致的低应力局部塑性变形来解释。

In the theoreitical analysis, the effective modulus E was used for the stresses which exceed the proportionallimit.
