WebMar 9, 2015 · 3.1. Gassner Curve and Stiffness Degradation. The classical stress-life curve (S-N) which is used to characterize the fatigue properties at CALs, can be used in a modified version for VALs to present life results, by plotting the maximum peak stress (S max) versus the number of cycles until failure (N). The resultant curve is known as Gassner ...
