中文摘要：
引入了二阶取向张量来描述流动诱导纤维取向分布，利用伽辽金法建立了流动诱导纤维取向的有限元求解方程，分别采用Hand闭合近似模型和Hinch-Leal闭合近似模型，对典型的注射模平面流动行为进行了纤维取向的数值模拟。结果表明纤维的取向分布和取向程度与其受到的剪切历史和剪切速率密切相关，剪切速率是决定纤维取向分布的重要因素之一。
英文摘要：
In this paper, the 2nd order orientation tensor was introduced to represent flow-induced fiber orientation distribution. A finite element equation of fiber orientation was formulated by means of Galerkin method. Using linear Hand and H＆L models the representative planar flow behavior in the injection mold was simulated. It was concluded that the degree and distribution of fiber orientation were mainly determined by the shear rate and history acting on the polymer, with the shear rate being more important.
