现有薄壁圆筒设计规范已不能满足现代工程精度,工程断裂力学的发展和应用为提高强度计算公式的精度提供了有利条件。因此,本文在分析有关公式使用精度的基础上,用满足现代工程精度要求的计算公式重新建立了安全壁厚计算式,并论汪了它的显著经济效果。一、关于基本公式的讨论由弹性理论知道,受均布内压的等厚度封
The existing design specifications of thin-walled cylinders can no longer meet the modern engineering precision. The development and application of engineering fracture mechanics provide favorable conditions for improving the accuracy of strength calculation formulas. Therefore, based on the analysis of the accuracy of the use of the formula, this paper re-established the calculation formula of the safe wall thickness with the calculation formula that meets the requirements of the modern engineering precision, and discussed Wang’s remarkable economic effects. First, the discussion about the basic formula is known from the theory of elasticity.
