| 摘 要： | 对于橡胶材料,高玉臣在1990年和1997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,揭示了这类材料的大变形特征并得出了对材料常数的限制条件.

| Abstract: | 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. |
