The formula to calculate the Hertz Pressure (P) is:
\[ P = \frac{3 \cdot F \cdot (1 - \nu^2)}{2 \cdot \pi \cdot a^2 \cdot E} \]
Where:
Hertz pressure is a measure of the contact pressure between two elastic bodies in contact. It is named after the German physicist Heinrich Hertz, who developed the theory of contact mechanics. Hertz pressure is used to describe the stress distribution in the contact area of two bodies, such as a ball and a flat surface, or two spheres. This concept is important in various fields, including mechanical engineering, materials science, and tribology, as it helps in understanding the behavior of materials under load and in designing components that can withstand high contact pressures without failure.
Let's assume the following values:
Using the formula:
\[ P = \frac{3 \cdot 1000 \cdot (1 - 0.3^2)}{2 \cdot \pi \cdot 0.01^2 \cdot 200000000} \approx 0.0022 \]
The Hertz Pressure (P) is approximately 0.0022 Pa.
