土工有限元中弹塑性分析的实现

Accomplishment of Elastic-plastic Analysis in Geotechnical FEA

为了实现土工有限元的弹塑性分析 ,文章讨论了在Super-Sap中如何实现弹塑性分析的方法 ,重点介绍了利用现成的Super-Sap有限元软件和三维弹塑性有限元计算程序对岩土类材料实现弹塑性分析的原理与步骤。计算实例表明 。

In order to realize elastic-plastic analysis in geotechnical FEA, in this paper, firstly, the method how to realize elastic-plastic analysis in Super-Sap is discussed. Then, this paper stresses to introduce the principle and the steps used to achieve the accomplishment of elastic-plastic analysis in Super-Sap. Finally, an engineering practice is given to prove that the geotechnical FEA elastic-plastic analysis and visualized post-processing can come true by it rapidly.
