Fatigue properties of wood at different load ratios tested at 50 Hz and 20 kHz Ermüdungseigenschaften von Holz bei unterschiedlichen Lastverhältnissen geprüft bei 50 Hz und 20 kHz

Materialwissenschaft und Werkstofftechnik, Volume 53, Issue 3, Page 344-354, March 2022., 2022
Fatigue properties of sycamore maple at different load ratios are investigated, and a Haigh diagram is plotted. In addition to servo‐hydraulic testing at 50 Hz, the ultrasonic fatigue testing technique – operating at 20 kHz under tension‐compression loading – is for the first time employed to investigate the fatigue properties of wood.
