研究了引入率相关模型含液多孔介质应变局部化双重内尺度律的特征以及相互作用,此时材料应变局部化分析结果的正则性得到保证,但同时也出现了双重内尺度律参数的相互作用问题,且内尺度律预测也成为问题分析的难点.提出了引入率相关模型后内尺度律预测的一个基本方法,并进行了多孔材料的稳定性分析.同时也讨论了不同情况下实波速存在的条件以及给定渗透系数对应的实波速存在波数区间.最后通过数值算例对理论预测的正确性进行了验证.
The characteristics and interactions of the double internal scale law of strain localization in fluid-filled porous media are studied. At the same time, the regularity of the results of material strain localization analysis is guaranteed, but also the interaction of the dual internal scale parameters And the prediction of inner scale law also becomes a difficult point in the analysis of the problem.The paper presents a basic method of predicting the inner scale law after introducing the correlation model and carries out the stability analysis of the porous materials.At the same time, And the wave number interval exists for the real wave velocity corresponding to the given permeability coefficient.Finally, numerical examples are used to verify the correctness of the theoretical prediction.
