Calculate k Stress Concentration Factor
Calculating the k stress concentration factor is crucial in mechanical engineering to predict stress levels in components with geometric discontinuities. It helps ensure the safety and longevity of structures under various loading conditions.
How to Use This Calculator
- Enter the diameter of the component and the diameter of the hole.
- Select the type of hole (Type 1, 2, or 3).
- Click ‘Calculate’.
Formula & Methodology
The k stress concentration factor is calculated using the formula: k = 1 + (2 * sqrt(d/D) / (1 – sqrt(d/D))), where d is the hole diameter and D is the component diameter.
