When we do fatigue life analysis we need to use the S-N curve for it which requires Stress amplitude (Y-Axis on S-N Curve). When we are performing FEA in ANSYS, we get the output in terms of von Mises or principal stress. My question is how to predict this stress Amplitude value from FEA result...
Hi All, I am currently doing FEA Simulation of Random Vibration of the Wooden Crate by using PSD Curve data. Usually, in the case of steel material, we calculate the ‘3 σ Von-Mises Stress’ value & these values we will compare with the Endurance strength of the Material to comment on Pass-Fail...
