摘要
对我国球罐角变形的研究成果进行了综述,并以实测值和有限元计算值为依据对四个典型的球罐角变形附加应力计算式进行了比较和评价。
A summary of the achievements in studying spherical shells with angle deformations has been made. Based on both the measuring stres and stresses calculated from finite element, the evaluation and comparison among four typical formulae calculating the additional stresses in spherical shells with angle deformations were conducted in detail.
