Fatigue Analysis | Single Crank | Basics of Ansys (ME) Tutorial 30

Fatigue Analysis
“Life of structure when it is subjected to repetitive load” Failures were observed even after designing the components with maximum stress value well below yield / ultimate stress. Later it was concluded that the failure is because variation of load with respect to “time” not being taken in to account. Tests were then carried out for time varying loads. Results proved that the component fails at values below yield stress when subjected to time varying load. Fatigue accounts for 90% of failures in mechanical engineering application. Typically these failures are observed at stress concentration points or welded, bolted joints etc. Fatigue provides life, damage, and factor of safety information under cyclic loading and uses a S-N (stress-life) or E-N (strain-life) approach.

The type of approch in problem statement is strain life u calculate on stress life

[anandalamichhane]

Sir please can you help me with mechanical apdl setup problem I'm just stuck in it please

[abhisheknaththakur]

Thank you so much sir. But I want to find out the same in transient structural module. I am finding difficult in setting time step and size. Can you make one video transient structural analysis. Thanks in advance

[anhtuannguyen]

Thanks a lots sir, but can I have those files that you use to import to geometry? I just want to practice, following what you've done in the video.
