The formula to calculate the maximum stress at the crack tip is:
\[ \sigma_{\text{max}} = k \cdot \sigma \]
Where:
The maximum stress at the crack tip is the maximum amount of stress at the tip of a crack.
The stress concentration factor is a measure of the degree to which external stress is amplified at the tip of a crack.
Applied stress is the stress applied to a material, denoted by the symbol \(\sigma\).
Let's assume the following values:
Using the formula:
\[ \sigma_{\text{max}} = 22 \cdot 93.3 \approx 2052.6 \, \text{Pascal} \]
The maximum stress at the crack tip is approximately 2052.6 Pascal.
