k-g model meaning in English
k-g模型
Examples
- All models can predict the attached and little separation flows . for the high angle - of - attack separated flows with distinct history effects , the j - k and k - g models perform better than b - l model . for multi - body and multi - block mesh system , model k - g , which does not need the distance normal - to - wall , performs much better adaptability for complex geometries
所有模型都可以很好地模拟附体及和小分离流动;对于具有明显上游历程效应的大迎角分离流动， j一k和k - s模型的模拟能力较强;对于多体干扰和多块网格系统， k - s模型无需计算网格单元至物面的垂直距离，具有较强的适应能力，且计算效果最佳。 - Using 3d 20 - node iso - parameter , 3d 12 - node infinite element and 3d 16 - node interface element , a coupled numerical approach for pile group - soil system under lateral loads is set up . a corresponding three - dimensional , nonlinear and elastic - plastic program ( epagpll ) , include two materials and four nonlinear constitutive relations , is worked out by fortran 90 computer language . in the analysis the nonlinear e - model , k - g model and cambridge model with two yield surfaces are employed in the analysis of near - field soil , and the nonlinear analysis method is used in the piles - soil interface and distant - field soil
本人用有限元进行桩体和近域土的分析，对远域土体采用无限单元，在桩土之间采用接触面单元，建立了平面8节点环状单元6节点无限元6节点接触面单元相耦合的数值计算模型；针对竖直受力桩的流变分析，本人用内嵌于autocad的vba语言编制了前处理程序，可以快速形成包括网格、节点编号、单元编号在内的数据文件，供计算程序使用；同时在前人关于流变问题研究的基础上，引进土体非线性流变本构模型，利用有限元、无限元、接触面单元相结合的方法，用c + +语言编制了相应的计算程序。
