Notch Sensitivity Factor Solution

STEP 0: Pre-Calculation Summary

Formula Used

Notch Sensitivity Factor = Increase of Actual Stress over Nominal Stress/Increase of Theoretical Stress over Nominal Stress
q = σ_an/σ_tn
This formula uses 3 Variables

Variables Used

Notch Sensitivity Factor - The Notch Sensitivity Factor is defined as the ratio of increase of actual stress over nominal stress to increase of theoretical stress over nominal stress.
Increase of Actual Stress over Nominal Stress - (Measured in Pascal) - The Increase of Actual Stress over Nominal Stress is the amount of stress increment in the actual value of stress over the nominal value of stress.
Increase of Theoretical Stress over Nominal Stress - (Measured in Pascal) - The Increase of Theoretical Stress over Nominal Stress value is the amount of stress increment in the theoretical value of stress over the nominal value of stress.

STEP 1: Convert Input(s) to Base Unit

Increase of Actual Stress over Nominal Stress: 80 Newton per Square Millimeter --> 80000000 Pascal (Check conversion here)
Increase of Theoretical Stress over Nominal Stress: 110 Newton per Square Millimeter --> 110000000 Pascal (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

q = σ_an/σ_tn --> 80000000/110000000

Evaluating ... ...

q = 0.727272727272727

STEP 3: Convert Result to Output's Unit

0.727272727272727 --> No Conversion Required

FINAL ANSWER

0.727272727272727 ≈ 0.727273 <-- Notch Sensitivity Factor

Notch Sensitivity Factor

Go Notch Sensitivity Factor = Increase of Actual Stress over Nominal Stress/Increase of Theoretical Stress over Nominal Stress

Fatigue Stress Concentration Factor

Go Fatigue Stress Concentration Factor = Endurance Limit of Notch Free Specimen/Endurance Limit of Notched Specimen

Notch Sensitivity Factor given Fatigue Stress Concentration Factor

Go Notch Sensitivity Factor = (Fatigue Stress Concentration Factor-1)/(Theoretical Stress Concentration Factor-1)

Fatigue Stress Concentration Factor given Notch Sensitivity Factor

Go Fatigue Stress Concentration Factor = 1+Notch Sensitivity Factor*(Theoretical Stress Concentration Factor-1)

Theoretical Stress for Fluctuating Load

Go Theoretical Stress = Nominal Stress*Theoretical Stress Concentration Factor

Notch Sensitivity Factor Formula

Notch Sensitivity Factor = Increase of Actual Stress over Nominal Stress/Increase of Theoretical Stress over Nominal Stress
q = σ_an/σ_tn

What is endurance limit?

The fatigue or endurance limit of a material is defined as the maximum amplitude of completely reversed stress that the standard specimen can sustain for an unlimited number of cycles without fatigue failure.
