Stress Concentration Factor Calculator

Formula

The formula to calculate Stress Concentration Factor (Kt) is:

\[ Kt = \frac{PS}{NS} \]

Where:

\(Kt\) is the Stress Concentration Factor
\(PS\) is the peak stress
\(NS\) is the nominal or average stress

What is Stress Concentration Factor?

The Stress Concentration Factor (Kt) is a measure of the increase in stress at a point in a material where there is a sudden change in geometry, such as a hole, notch, or fillet. It is calculated by dividing the peak stress by the nominal stress.

Example Calculation

Let's assume the following values:

Peak Stress (PS) = 150 MPa
Nominal Stress (NS) = 100 MPa

Using the formula to calculate Stress Concentration Factor (Kt):

\[ Kt = \frac{150}{100} = 1.5 \]

The Stress Concentration Factor is 1.5.
