摘要
本文利用能量法中的瑞利—里茨法对外壁受刚性约束的外压圆柱壳的稳定性进行了理论分析和计算。针对这类圆柱形壳的可能失稳形式,特别设计出了三个较为合理的位移函数,以此来描述壳体的失稳,从而导出了外壁受刚性约束的外压圆柱壳失稳时的临界压力计算式,并给出了求解问题的计算步骤和实施方案。
<ABSTRACT>: Using the Rayleigh-Ritz Method ,the stability of the externally pressured cylinderical lining shells inside rigid cylinders is analyzed and 'Calculated theoretically. Three displacement functions, which may be more reasonable,are presented to describe the disstabilization of the shells of this kind, and,based on them,the equations for the calculation of the critical pressure of disstabilization are developed. The scheme and procedure for solving these equation are given.
