Analysis of critical global energy error limit of gravity dam stresses using adaptive finite element method
Journal Title: Science Paper Online - Year 2008, Vol 3, Issue 7
Abstract
In this paper, the research on energy error limit of gravity dam stress analysis using adaptive finite element method (FEM) has been carried out. Through the stress analyses in many types of gravity dams with different dam height and its downstream and upstream slops the conclusion has been made that there exists a critical global energy error limit (CGEEL) in the course of dam stress analysis. Although variation of its value is slightly for various geometry of dam, the variation is small enough so that it does not affect CGEEL. It will be helpful for FEM analysis of gravity dam.
