... can be obtained with closed-loop control of vibration amplitude and resonance frequency. Self-heating of test specimens can be suppressed by intermittent (pulse-pause) loading. In the present work, the high-accuracy ultrasonic fatigue testing equipment developed at the University of Natural Resources...

... are compared using Kolmogorov-Smirnov tests. Ultrasonic fatigue testing is used to quantify fatigue properties of the builds from the different L-PBF machines under fully reversed loading conditions. Finally, fatigue performance is correlated to the defect distribution in builds across the three platforms...

...Gonzalo M. Dominguez Almaraz Ultrasonic fatigue tests were carried out on the aluminum alloy AISI 6061-T6, presenting different values for the principal surface roughness parameters: R a , R q , and R z . For fatigue life comprised between 3 × 10 5 ∼ 6 × 10 6 cycles, crack initiates at the specimen...
