Theoretical Stress for Fluctuating Load Solution

STEP 0: Pre-Calculation Summary

Formula Used

Theoretical Stress = Nominal Stress*Theoretical Stress Concentration Factor
σ = σ_o*k_t
This formula uses 3 Variables

Variables Used

Theoretical Stress - (Measured in Pascal) - Theoretical stress is defined as the product of theoretical stress concentration factor and nominal stress.
Nominal Stress - (Measured in Pascal) - Nominal Stress is the value of the stress at the minimum cross-section.
Theoretical Stress Concentration Factor - Theoretical Stress Concentration Factor is defined as the ratio of the highest value of actual stress near discontinuity to nominal stress obtained by elementary equations for minimum cross-section.

STEP 1: Convert Input(s) to Base Unit

Nominal Stress: 25 Newton per Square Millimeter --> 25000000 Pascal (Check conversion here)
Theoretical Stress Concentration Factor: 3 --> No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

σ = σ_o*k_t --> 25000000*3

Evaluating ... ...

σ = 75000000

< 5 Notch Sensitivity for Fluctuating Loads Calculators

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

Theoretical Stress for Fluctuating Load Formula

Theoretical Stress = Nominal Stress*Theoretical Stress Concentration Factor
σ = σ_o*k_t

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.
