5.3.7 Assign Constitutive Models and Properties设定基本模型和参数
A constitutive model is associated with a specific region of the grid through the MODEL command. The mechanical constitutive models available in are discussed in Appendix G. The following keywords are available to assign the appropriate model.
通过MODEL命令设定一个特定网格区域的基本模型,用在FLAC3D的物理基本模型将在附录G中讨论,下面的关键字可以用来设置适当的模型。
Mechanical Model物理模型

Thermal Model (available only for thermal model option, see Appendix J)
th_isotropic isotropic thermal conductivity均质热导体
th_null null zone for heat conduction 热导空单元
Properties are assigned for each model through the PROPERTY command. For the strain-hardening/softening model, properties can depend upon accumulated plastic strain as defined through the TABLE command. Fluid flow properties (fluid bulk modulus or Biot’s modulus) are prescribed with the INITIAL command. Mass densities for the material and the fluid are also prescribed with the INITIAL command.
通过PROPERTY命令来设置各个模型的参数。对于应力-硬化/软化模型,参数依赖于通过TABLE命令定义的积聚的塑性应力。 |
