耐久性设计中的裂纹检修成本的预测

Prediction on Crack Overhauling Rost in Durability Design

摘要: 本文提出了耐久性设计中确定结构裂纹检修尺寸X1的条件.通过对裂纹长度超越概率分布函数的讨论导出了经济寿命期内的裂纹检修成本的解析表达式,从而达到控制裂纹检修成本的目的.

Abstract: This paper put forward the requirements determing crack overhauling demension X 1 of stuctures on durability design.And discusses that from the distribution function of transcendental probability of a crack length derived the formula of overhauling rost during economic life.By that means we can control the overhauling rost during economic life.
