几种适合超高分子量聚乙烯的力学模型

Several mechanical models fit to UHMWPE

超高分子量聚乙烯作为一种粘弹性体聚合物,在使用过程中,机械性能既有弹性的一面,也有粘性的一面。以粘弹性(粘塑性)为基础,从线性和非线性角度出发,分别介绍了几种适合超高分子量聚乙烯的力学模型,为以后采用有限元分析方法研究超高分子量聚乙烯机械性能提供理论帮助。

As a kind of high visco - elastic polymer when used, UHMWPE presents both viscosity and elasticity in mechanical property.In this paper, we introduced several mechanical models which fit to UHMWPE based on linear and nonlinear visco-elastic(visco - plastic) theorys. The goal is to provide suitable theory for later studying mechanical character of UHMWPE with FEM method.
