Experiment: Fatigue Testing - iMechanica
imechanica.orgthe machine. 2. Fatigue Test: The lab TA will conduct a constant amplitude, tension-tension fatigue test on a dogbone sample up to fracture. Measure the sample prior to testing and record its’ dimensions; document the testing parameters used (waveform, maximum & minimum load, frequency, etc.). 3. Miner's Law Problem - see Lab Requirements
Ductile vs. brittle fracture - gpmanesar.ac.in
www.gpmanesar.ac.in(stress — number of cycles to failure) Fatigue properties of a material (S-N curves) are tested in rotating-bending tests in fatigue testing apparatus: Result is commonly plotted as S (stress) vs. N (number of cycles to failure) Low cycle fatigue:high loads, plastic and elastic deformation High cycle fatigue:low loads, elastic deformation (N ...
