摘要

基于虚内键模型，推导出三维条件下虚内键演化函数的四阶弹性张量，对虚内键密度演化函数中的两个参数进行研究，建立单轴压缩下岩石数值模型，得出两参数对岩石应力-应变全过程曲线影响的一般性规律，实现对均质大理岩试样应力-应变全过程曲线的数值模拟。数值结果表明，基于虚内键模型的均质岩石应力-应变全过程曲线与力学试验结果较为吻合。从而证明了用虚内键模型探讨岩石材料本构关系的适用性与可行性，为研究岩石本构关系提供了一个新思路。

Abstract

Based on the virtual internal bond (VIB) model

a fourth-order elastic tensor of the VIB evolution function is deduced. Two parameters in the evolution of VIB density are studied

and a numerical model of rock is developed under uniaxial compression. A general law of the influence of these two parameters on the whole stress-strain curve is obtained

and a stress-strain curve of homogeneous marble sample is simulated by the VIB model. Numerical results show that the stress-strain curve is in good agreement with experimental results. The applicability and feasibility of the VIB model for the constitutive relation of rocks are proved

which provides a new way to study the constitutive relationship.
