Calculate Stress Concentration Factor
Expert Guide to Calculate Stress Concentration Factor
The stress concentration factor (SCF) is a crucial parameter in mechanical engineering, used to determine the peak stress in a component due to the presence of geometric discontinuities. Understanding and calculating the SCF is vital for designing safe and reliable structures.
How to Use This Calculator
- Enter the diameter and radius of curvature of the component.
- Enter the applied load.
- Click ‘Calculate’.
Formula & Methodology
The SCF is calculated using the formula: SCF = 1 + 2 * (a / r) * (1 – (a / r) * (1 – √(1 – (a / r)^2))), where ‘a’ is the radius of the hole and ‘r’ is the radius of curvature.
