一种新的等参数弯管单元——线性分析

Linear Analysis——a New Lsoparameter pipe Elbow Element

摘要: 管道弯头的强度研究是个很重要的问题。本文采用有限单元法中一种新的、有效的等参数四节点弯管单元，分析了弯头的应力与变形。导出了线性分析的应变位移矩阵及刚度矩阵。

Abstract: It is important to study the strength of the pipe elbow.The article analyses the stress and the deformation of elbows by taking one of the finite element methods, a new and effective four-node isoparameter pipe elbow element, infering the strain-displacement matrix and stiffness matrix in linear analysis.
