ONE FORMULA, ONE ANSWER
Average Axial Stress Calculator
Check average axial stress in a specimen or a bar. Choose input units and calculate one value within the stated conditions.
Inputs
Calculations run in this browser. Scientific notation such as 1.2e-3 is supported. Do not group thousands.
Result
Average axial stress σ_avg
Enter values and select Calculate.
σ_avg = F / A
Assumptions
Use A>0 and a centered axial load. The result is the cross-sectional average. Notch, hole and local stress concentrations are excluded. Tension is positive and compression is negative.
Displayed values are floating-point approximations. Measurement uncertainty and design safety factors are not calculated.
