为了描述填充弹性体的非弹性力学行为，建立了一个基于微观结构的单轴加载材料模型。这个一维材料描述的推广到一个完全三维的本构模型已经完成了使用的概念，代表性的方向。广义模型与几种橡胶化合物的循环单轴拉伸和压缩试验以及简单的剪切测量结果吻合得很好。FE实现使技术部件的有限元模拟成为可能，尽管原始输入模型仅预测单轴载荷的材料行为。(c)2010爱思唯尔有限公司保留所有权利。
To describe the inelastic mechanical behavior of filled elastomers a microstructure-based material model for uniaxial loadings has been developed. The generalization of this one-dimensional material description to a fully three-dimensional constitutive model has been accomplished by using the concept of representative directions. The generalized model shows a very good agreement with cyclic uniaxial tension and compression tests as well as simple shear measurements for several rubber compounds. The FE-implementation enables finite element simulations of technical components though the original input model predicts the material behavior for uniaxial loadings only. (c) 2010 Elsevier Ltd.
