| 摘 要： | 本文根据Green-Rivlin提出的Frechet级数,提出了一个兼具长时粘流效应及短时粘弹效应的一维非线性本构方程,并对一种沥青混合料采用蠕变试验方式拟合了本构方程的参数向量。拟合结果表明:这一本构方程形式简洁,物理意义清晰,易于拟合,并对不同应力历史下的应变响应具有广泛的适用性。

| Abstract: | A one-dimensional nonlinear constitutive equation for describing both long period viscous effect and short period elastic effect has been presented according to Frechet series given by Green-Rivlin. The parameter vers of constitutive equation were determined by means of curvilinear regression of experimental data in the creep tests for a sort of asphalt mixture.The results indicate that the constitutive equation is valid for the strain response with different histories of stress. |
