摘要
借助不可压橡胶类材料应变能函数,通过引入泡沫材料孔隙度,推导出了泡沫橡胶的本构方程。基于泡沫橡胶材料的单轴压缩实验结果,拟合确定了本构模型的参数,模型预测结果与实验结果吻合的比较好。
The new constitutive model of foam rubber materials is established considering compressible caused by the porosity of foam materials, the constitutive data for the new model is fitted and the uniaxial compression experiment is utilized to prove the feasibility of the constitutive equation produced in this paper. The model is in good agreement with the experimental results.
