Fatigue

• Local Stress-Strain Fatigue Method ( ε-N ) Although most engineering structures and machine components are designed such that the nominal stress remains elastic (S_n < σ_ys) stress concentrations often cause plastic strains to develop in the vicinity of notches where the stress is elevated due to the stress concentration effect.

• Stress Concentration Factors for Flat Plates and Cylinders : In a structure or machine part having a notch or any abrupt change in cross section, the maximum stress will occur at this location and will be greater than the stress calculated by elementary formulas based upon simplified assumptions as to the stress distribution.
