The formula to calculate the Rivet Diameter (d) is:
\[ d = \sqrt{\left( \frac{4F}{\pi \tau} \right)} \]
Where:
Let's say the shear force (F) is 500 N and the shear strength (τ) is 250 N/mm². Using the formula:
\[ d = \sqrt{\left( \frac{4 \times 500}{\pi \times 250} \right)} \]
We get:
\[ d = \sqrt{\left( \frac{2000}{785.398} \right)} = \sqrt{2.546} = 1.59 \text{ mm} \]
So, the rivet diameter is approximately 1.59 mm.
