FEM Analysis on the Collapse Property of Casing
-
摘要: 運用有限單元分析方法詳細考察了承受均勻外壓力的樣本油套管在不同橢圓度、不同壁厚不均(或稱偏心度)、以及不同橢圓度和壁厚不均組合等初始幾何缺陷的情況下的應力變化及其分布,并作出相應的初始幾何缺陷與應力變化的曲線.Abstract: Finite Element Method (FEW is applied to research and analyse the distribution of stresses in a sample casing under uniform external pressure, which has various initial geometric imperfections (ovality and eccentricity).
