摘要
对于橡胶材料 ,高玉臣在 1 990年和 1 997年分别提出两个本构关系 ,一个是将应力偏量与静水应力分离 ,另一个是将拉应力与压应力分离 .本文提出了一种简单的橡胶材料本构关系 ,通过对立方体单元的典型大变形分析 。
Two kinds of elastic laws have been adopted by Gao in 1990 and 1997 to analyze the deformation fields near a crack tip. One of them contains the response to volume change and shape change; the other contains the response to extension and compression. In this paper a simple elastic law of rubber material is proposed. We examined some typical deformation of a cubic element, therefore the mechanical behavior of this kind of material is revealed, and the restrictions on constitutive parameters are discussed.
