摘要
研究动态剪切试验方式进行应变扫描测试,表明温度是橡胶材料性能的关键因子;相同材料多次测试结果对比说明测试过程中会出现Payne效应和Mullins效应,并通过多次测试的方法消除Mullins效应的影响;根据剪切模式受力方式推导了几种超弹性本构模型公式并与单轴拉伸数据拟合结果进行了对比。
In this paper, strain sweep test of rubber compound by using dynamic shearing was discussed,and the test result indicated that temperature was a key factor influencing the rubber material properties. The results of several tests of the same material showed Payne effect and Mullins effect. The influence of Mullins effect could be eliminated by multiple testing. Several hyperelastic constitutive model equations were derived based on shear force mode,and compared with the modeling results from uniaxial tension data.
