三维H-自适应误差分析在焊接工程中的应用

Application of 3-dimensional H-adaptive error estimation in welding engineering

提出了一个与有限元分析和自适应网格管理前后串联的误差分析方法,该方法可提供局部和系统的误差预测,并且与问题的属性无关,可用来计算许多标量如温度、位移、有效应力,应变等.重点研究此法在焊接的热分析中的应用,得到了有益的结论.

A posteriori error estimation method which works in tandem with finite element analysis and adaptive mesh management is presented. It can be used to compute many appropriate scalar quantities such as temperature, displacement, effective stress and effective plastic strain.
