Mean Stress for Fluctuating Load Solution

STEP 0: Pre-Calculation Summary

Formula Used

Mean Stress for Fluctuating Load = (Maximum Stress at Crack Tip+Minimum Stress at Crack Tip)/2
σ_m = (σ_max+σ_min)/2
This formula uses 3 Variables

Variables Used

Mean Stress for Fluctuating Load - (Measured in Pascal) - Mean Stress for Fluctuating Load is defined as the amount of mean stress acting when a material or component is subjected to fluctuating stress.
Maximum Stress at Crack Tip - (Measured in Pascal) - Maximum Stress at Crack Tip is the maximum amount of stress at the tip of a crack.
Minimum Stress at Crack Tip - (Measured in Pascal) - Minimum Stress at Crack Tip is the minimum amount of stress at the tip of a crack.

STEP 1: Convert Input(s) to Base Unit

Maximum Stress at Crack Tip: 180 Newton per Square Millimeter --> 180000000 Pascal (Check conversion here)
Minimum Stress at Crack Tip: 40 Newton per Square Millimeter --> 40000000 Pascal (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

σ_m = (σ_max+σ_min)/2 --> (180000000+40000000)/2

Evaluating ... ...

σ_m = 110000000

STEP 3: Convert Result to Output's Unit

110000000 Pascal -->110 Newton per Square Millimeter (Check conversion here)

FINAL ANSWER

110 Newton per Square Millimeter <-- Mean Stress for Fluctuating Load

< 9 Flat Plate against Fluctuating Loads Calculators

Smaller Width of Flat Plate with Shoulder Fillet given Nominal stress

Go Smaller Width of Plate = Load on Flat Plate/(Nominal Stress*Thickness of Plate)

Thickness of Flat Plate with Shoulder Fillet given Nominal Stress

Go Thickness of Plate = Load on Flat Plate/(Nominal Stress*Smaller Width of Plate)

Nominal Tensile Stress in Flat Plate with Shoulder Fillet

Go Nominal Stress = Load on Flat Plate/(Smaller Width of Plate*Thickness of Plate)

Major Axis of Elliptical Crack Hole in Flat Plate given Theoretical Stress Concentration Factor

Go Major Axis of Elliptical Crack = Minor Axis of Elliptical Crack*(Theoretical Stress Concentration Factor-1)

Minor Axis of Elliptical Crack Hole in Flat Plate given Theoretical Stress Concentration Factor

Go Minor Axis of Elliptical Crack = Major Axis of Elliptical Crack/(Theoretical Stress Concentration Factor-1)

Load on Flat Plate with Shoulder Fillet given Nominal Stress

Go Load on Flat Plate = Nominal Stress*Smaller Width of Plate*Thickness of Plate

Theoretical Stress Concentration Factor

Go Theoretical Stress Concentration Factor = Highest Value of Actual Stress near Discontinuity/Nominal Stress

Theoretical Stress Concentration Factor for Elliptical Crack

Go Theoretical Stress Concentration Factor = 1+Major Axis of Elliptical Crack/Minor Axis of Elliptical Crack
