单向复合材料纵向弹性模量E_x另一细观计算公式

Another calculation formula for longitudinal elastic modulus of unidire ctional composite

本文从细观力学角度 ,采用惠特尼———瑞莱 (Whitney -Riley)典型单元体模型 ,用材料力学分析方法给出单向复合材料纵向弹性模量Ex 的另一种计算公式。该计算公式比常用的模量混合律公式有所改进。

In this paper another elastic modulus of unidirectional composite materials has been establised according to Whitney-Riley model.On the basis of the mechanics of materials,the result is proposed and it improves the common modulus mixing formula.
