岩石拉伸随机破坏的模拟计算

Computer modelling of stochastic rock failure during tensile loading

针对岩石中存在初始损伤,采用随机正态分布理论模拟杨氏模量及泊松比,在有限元计算的基础上,模拟岩石拉伸的随机破坏模式、拉伸蠕变曲线和损伤曲线,并与试验结论进行对比分析。

For the sake of the primary damage of rock , stochastic method is adopted in this paper tc model the Young's modlus and Possion rate of rock. In order to acquire the stochastic failure models、the creep curves、the damage curves of rock during tensile loading, the FEM theory is used. Also, the conclusion of calculation is compared with tests.
