摘要
分别以弹簧、滑片和胶结杆来代表固体的基本特性即弹性、塑性和脆性.并在此基础上,提出了能客观地反映岩样变形和破坏过程的二元介质模型.多个算例结果表明,调整二元介质模型的参数,可以描述多种类型的应力应变曲线.
Solid′s mechanical behavior includes elasticity, plasticity and brittleness which are denoted by spring, gliding slab and cementation bar respectively. Based on this assumption, a binary medium model which can describe the complex process of rock′s deformation and failure is proposed. Computed examples show that this model can duplicate variant stress-strain behaviors by adjusting its parameters.
