In addition , something looks not quite real in curtain presentation , which may be solved by introducing imperfect elastic model 另一方面,窗帘的效果也有一些不真实的地方,这主要是要靠引入非弹性模型来解决。
This paper adopts the ducon - zhang soil model , establish a non - linear elastic model of retaining structure of deep foundation pit , and draw up a plane finite element program 本文采用了邓肯-张土体模型,建立了深基坑支护结构的非线性弹性模型,编制了平面有限元程序。
In order to establish the nonlinear elastic model of qi loess , the hump curve was used to stimulate both the softening stress - strain curve and the volume deformation curve 对软化型应力应变曲线提出用驼峰曲线模拟,对体变曲线也提出用能反映剪胀的驼峰曲线模拟,建立了q1黄土的非线性弹性k 、 g模型。
Duncan - chang model , an non - linear elastic model , is widely used in engineering . because the model reflects the main rules of the deformations of soils , and parameters can be gained from triaxial tests 由于邓肯?张模型反映了土体变形的主要规律并且其各项参数易于从常规三轴试验求得而在工程实践中被广泛应用。
A two - dimensional finite element program , in digital visual fortran version 6 . 0 language , is developed for the numerical computation . due to time limit , elastic modeling is adopted while writing program 在此基础上用digitalvisualfortran语言编制了相应的二维弹性有限单元程序,并通过算题论证了程序的准确性。
