摘　　要：利用XJTUDIC三维数字散斑动态应变测量分析系统和拉伸实验机对废旧轮胎胎面胶进行了拉伸实验,得到了应力-应变曲线和应变云图等结果以进行胎面胶的材料特性表征。使用商业有限元分析软件ABAQUS并分别选用超弹性材料模型Yeoh模型和Mooney-Rivlin模型对实验结果进行拟合,发现Mooney-Rivlin超弹性材料模型的模拟结果与实验结果很吻合。同时得出了Mooney-Rivlin材料模型的参数。Uniaxial tensile tests for tread of waste tire are carried out with XJTUDIC 3D digital speckle dynamic strain measuring and analyzing system.Stress-strain curves,strain contours and other information are recorded for the purpose of material characterization of the tread.Commercial FEA software package ABAQUS is used to implement the material modeling taking advantage of the uniaxial tensile test results.Hyperelastic models Yeoh model and Mooney-Rivlin model are chosen for the purpose of fitting with experimental data.It is found that simulation results from the Mooney-Rivlin model are in good agreement with experimental results.Specific material parameters for the Mooney-Rivlin model are also obtained for the tire tread.
