By H. Trescas subdued condition and Lagrange Multiplier,an optium design method for these thick-walled cylindrical pressure vessels is obtained. We also provid a group of practical fosmulae for design and manufacture departments.

• Tresca屈服条件及Lagrange乘数法,对这类厚壁容器的优化设计方法进行了探讨,导出了一系列实用的计算公式,供设计及制造部门参考。
