| 摘 要： | 利用虚内键模型理论（virtual internal bond model，简称VIB），由岩石单轴压缩损伤本构方程和虚内键联接法则方程的相似性，提出了岩石单轴压缩破坏的虚内键密度演化函数 ，通过含虚内键密度演化方程的弹性张量 ，实现了岩石单轴压缩应力-应变全过程曲线的数值模拟。数值模拟结果表明，通过参数的合理选取，虚内键模型理论可以模拟不同岩样的全过程曲线。 |
| 关 键 词： | 虚内键 演化函数 单轴压缩 应力-应变曲线 |

| Abstract: | Based on virtual internal bond model (abbreviated as VIB) for isotropic materials, and enlightened by the similarity of the damage constitutive model of rock under uniaxial compression and the cohesive force law of VIB, a virtual internal bond density evolution function of rock under uniaxial compression is suggested; and then the elastic tensor is formulated. Finally, it is successfully to simulated the complete curve of rock under uniaxial compression. The simulation results show that the VIB model can simulate different kinds of rock sample if the parameters are selected well. |
| Keywords: | virtual internal bond model evolution function uniaxial compression stress-strain curve |
