聚合物熔体非牛顿行为及其本构方程

Non-Newtonian Behavior for Polymer Melts and Constitutive Equations

本文研究了成型加工过程中聚合物熔体的流变特性及其表征,探讨了熔体的非牛顿行为与本构方程的关系。对目前常用的一些本构方程的来源及其发展作了简要的述评,并就其特点和应用进行了初步的分析和讨论。

The general rheological properties of polymer melts during shaping and processing are investigated, and the relationship between the Non-Newtonian behavior of the melts and constitutive equations is discussed in this paper. The source and development for some constitutive equations which are often used now are reviewed, and the features and applications of these equations are also analyzed and discussed.
