摘要
概述橡胶材料超弹性本构模型的选取及参数确定。橡胶材料超弹性本构模型选取取决于材料试验、有限元分析适应性和橡胶制品力学计算精度三方面,模型参数确定方法主要有基于简单材料试验的本构理论计算法、基于完整材料试验的数值拟合法、根据已有橡胶材料特性的识别法和先进材料参数试验法。基于完整材料试验的数值拟合法和先进材料参数试验法是确定橡胶材料超弹性本构模型参数的发展方向。
The selection and parameter determination for hyperelastic constitutive models of the rubber material were summarized. The model selection depended on test of the material,adaptability of the finite element analysis and mechanics calculation accuracy of the rubber products. The methods of model parameter determination mainly were constitutive theory numeration based on simple material test,numerical fitting base on the full material test,identification method based on the tested rubber material characteristics and advanced material measurement technology. The numerical fitting based on the full material test and advanced material measurement technology were the mainstream methods.
