Research and Analysis on Plane 8-node Isoparametric Element

以圆形砂盘作为分析实例,通过Fortran程序和有限元软件ANSYS对试验过程进行了模拟,结合变分原理及工程计算力学基本理论,对模拟结果进行了对比分析。

Taking a circular sand disk as an analysis example,this paper makes a simulation on the test process by using Fortran program and ANSYS, a finite element software, and connecting with the variation principle and the basic theories of engineering calculation mechanics, compares and analyzes the simulation results.
