compaction band

Based on the conventional constitutive model,the bifurcation theory is applied to investigate the occurrence conditions of shear bands,compaction bands and dilation bands.

采用通用形式的本构模型,基于分叉理论探讨了剪切带、压缩带和膨胀带3种变形带的出现条件,详细分析了轴对称状态下临界硬化模量和变形带方向角随本构参数的变化特性,发现现有的分叉理论分析不能预测压缩带和膨胀带是受所选用的本构模型的限制;同时在轴对称条件下,不管是采用关联还是非关联流动法则,预测到压缩带或膨胀带只能在软化阶段才能产生;而当采用非关联流动法则时,在特定范围内,预测到剪切带可以在硬化阶段产生。

Recently,localized planar zones of deformation have been discovered in high-porosity rock,which are called compaction bands,shear bands and dilation bands.

近几年在野外和实验室都发现高孔隙岩石中局部化变形的压缩带、剪切带和膨胀带,是目前岩石力学、岩石物理和本构模型研究的热点之一。
