【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σｒ的变化情况，反映了界面特性对应力分布的影响．更多还原

【Abstract】 In this paper, stress distribution is obtained by employing the interface element to simulate the in terphase feature between fiber-matrix in single-ply laminarwhich consists of fiber arranged per iodically in the x-axis direction and matrix,and which is subjected to far-field transverso load the contour of stress u.. andradial stress a. in the yicinity of interphase are plotted for three different interphase cases. It is made known that the effect of interphase properties on stressdistribution is obvious.更多还原
