摘要
基于金属材料非对称循环疲劳极限的估算公式、R—S—N曲线方程和等寿命曲线方程 ,给出钛合金缺口试样的疲劳极限估算公式。
Based on the estimating formulae of unsymmetrical cycle fatigue limits, R-S-N curve equation and fatigue curve equation of constant life for metal materials, the estimating formula of unsymmetrical cycle fatigue limits, R-S-N curve equation and fatigue curve equation of constant life for titanium alloy notched specimens are put forward. Also presented are the R-S-N curves and fatigue diagrams of constant life for titanium alloy notched specimens by these equations.
