Gassner curve
WebMar 1, 2024 · Based on the measurements obtained in the LIT and two SSTs, the Gassner curve could be determined with PhyBaL SL showing a good correlation to the lifetime data obtained from additionally conducted SSTs. Furthermore, the results from LITs enable a rough estimation of the expected fatigue strength at 2 × 10 6 cycles. 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 ...
