How to Calculate Stress Amplitude?
Stress Amplitude calculator uses Stress Amplitude = (Maximum Stress at Crack Tip-Minimum Stress)/2 to calculate the Stress Amplitude, The Stress Amplitude, Sa, is the amount the stress deviates from the mean. It is sometimes called as alternating stress. Stress Amplitude is denoted by σa symbol.
How to calculate Stress Amplitude using this online calculator? To use this online calculator for Stress Amplitude, enter Maximum Stress at Crack Tip (σmax) & Minimum Stress (σmin) and hit the calculate button. Here is how the Stress Amplitude calculation can be explained with given input values -> -21.935 = (62.43-106.3)/2.
