    SOLUTION OF THE STRAIN-SOFTENING CONSTITUTIVE MODEL'S PARAMETERS

    • 摘要: 岩土介质的应变软化问题是岩土力学研究的难点和热点。当前,岩土工程界关于应变软化介质多用负指数分布或Weibull分布描述其本构关系,但对这种描述下本构方程参数求解的研究并不多见。文中对Weibull分布下的应变软化介质的本构方程建立一个参数求解模式,同时根据试验结果分析了本构曲线的适应性。

       

      Abstract: The research of strain-softening is a hot topic in engineering. Currently, the constitutive model for the strain-softening medium is described by negative exponent distribution or the Weibull's distribution law. However, there is few researche on how to get the parameters of the model. In this paper, parameters of the constitutive relation are solved.
