This article deals with the fatigue study for notched components, mainly through a stress-control approach. The article investigates the tension of specimens with stress raisers. The fidelity between the parameters K_{tn} derived from the book Peterson’s Stress Concentration Factors by Walter D. Pilkey, between its possible approximations of common use for some geometries will be verified. The work is divided into two phases: firstly, the concept of fatigue of materials, parameters and related factors that influence their resistance are introduced. Then, the results from the graphs of the book Peterson’s Stress Concentration Factors will be compared with graphs produced in MatLab environment through approximate formulas.

Abstract
This article deals with the fatigue study for notched components, mainly through a stress-control approach. The article investigates the tension of specimens with stress raisers. The fidelity between the parameters K_{tn} derived from the book Peterson’s Stress Concentration Factors by Walter D. Pilkey, between its possible approximations of common use for some geometries will be verified. The work is divided into two phases: firstly, the concept of fatigue of materials, parameters and related factors that influence their resistance are introduced. Then, the results from the graphs of the book Peterson’s Stress Concentration Factors will be compared with graphs produced in MatLab environment through approximate formulas.File | Dimensione | Formato | |
