Expansion upon ANSYS Random Vibration Fatigue Paper
ANSYS Fatigue Paper Expanding upon ANSYS Fatigue Slides Vibration fatigue calculations are “ballpark” calculations given uncertainties in S-N curves, stress concentration factors, non-linearity, temperature, surface finish, heat treatment, load sequence, multi-axis loading, mean stress, size, geometry and other variables. Perhaps the best that can be… Read more
