4.9.4.4 Failure curves for biaxial fatigue loads
The numbers of fatigue cycles to failure for biaxial stresses can be determined directly
from the calculations for the failure envelopes for various numbers of fatigue cycles.
The calculated biaxial failure curves for various minimum stresses S
cd,min
are given in
Figures 4.35 to 4.39.
