Hi Dave,
Since the Fatigue curves provided in Caesar are from ASME Div II which are based on Stress Amplitude versus Number of cycles and then a 0.5 Stress multiplier is applied then the Fatigue data within Caesar is a Stress Range versus Number of cycles. Am I right in assuming that Caesar calculates the stress intensities based on "Code Stress Ranges" using Code Stress intensification factors? If so then is it correct to compare these stress Intensities against the Stress Range versus Number of cycles fatigue data to establish the damage as the Code requires that "true" stress intensities be utilised.
