The formula to calculate the Range of Stress (Fatigue) is:
\[ \text{Range of Stress} = \text{Maximum Tensile Stress} - \text{Minimum Compressive Stress} \]
Range of Stress is the difference between maximum and minimum stress in a stress cycle during fatigue. Maximum Tensile Stress is the maximum amount of force per unit area acting onto the specimen so that it is prone to getting stretched. Minimum Compressive Stress is the minimum compressive stress in a cyclic load during fatigue.
Let's assume the following values:
Using the formula:
\[ \text{Range of Stress} = 50000000 - 40000000 \approx 10000000 \, \text{Pa} \]
The Range of Stress is approximately 10000000 Pa.
Maximum Tensile Stress (Pa) | Minimum Compressive Stress (Pa) | Range of Stress (Pa) |
