| Abstract: | 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. |
