For a completely reversed loading, amplitude of stress is maximum stress.
σ = 1100 × (105)−0.15
σ = 195.61 MPa
σ = 1100 × (105)−0.15
σ = 195.61 MPa

The S-N curve, also known as the stress-life curve. This curve represents the relationship between the applied stress amplitude and the number of cycles to failure for a given material. The S-N curve is typically obtained through fatigue testing, where specimens of the material are subjected to cyclic loading until failure occurs.
To estimate the fatigue life of a material under fully reversed loading condition, the following steps can be followed:
1. Determine the stress amplitude: The stress amplitude is the difference between the maximum and minimum stress in each cycle of loading. For fully reversed loading, the stress amplitude is equal to half the range of stress levels.
2. Identify the appropriate S-N curve: Different materials have different S-N curves, which depend on factors such as material composition, heat treatment, and surface condition. The S-N curve provides the relationship between stress amplitude and the number of cycles to failure.
3. Read the fatigue life from the S-N curve: Locate the stress amplitude value on the x-axis of the S-N curve and read the corresponding number of cycles to failure on the y-axis. This value represents the estimated fatigue life of the material under the given fully reversed loading condition.
It is important to note that the S-N curve is typically obtained for a specific stress ratio (the ratio between the minimum and maximum stress in each cycle of loading). For fully reversed loading, the stress ratio is -1, meaning that the minimum stress is equal to the negative maximum stress. If the stress ratio deviates from -1, the fatigue life estimation may need to be adjusted using appropriate correction factors.
