The Analysis of Calculated Dependences for Estimating the Sensitivity Coefficient of Structural Materials Relative to Stress Concentration in an Area of High-Cycle Fatigue

摘要

A method that allows plotting the fatigue curve for samples with stress concentration according to the results of smooth sample tests is considered. A group of equations is analyzed that allows the determination of the sensitivity of the material to the stress concentration in a region of high-cycle fatigue without using experimental data. An equation giving a satisfactory convergence of design and experimental data is selected.
