摘要: 本文利用界面单元的固有特性,将其用来模拟复合材料中纤维与基体之间的界面特征,计算了一个沿X轴方向纤维周期排列的单尾板,在横向载荷作用下的应力分布问题。给出了三相(纤维、基体和界面)特性各种配比时应力分布等高线图以及通过界面时径向应力σ_r的变化情况,反映了界面特性对应力分布的影响。

Abstract: In this paper,stress distribution is obtained by employing the interface element to simulate the interphase feature between fiber-matrix in single-ply laminar which consists of fiber arranged periodically in the x-axis direction and matrix,and which is subjected to far-field transverse load the contour of stress σ_sz and radial stress σ_r in the vicinity of interphase are plotted for three different interphase cases.It is made known that the effect of interphase properties in stress distribution is obvious.
