Fatigue Test of Aluminum Sample

Constant amplitude fatigue testing at LSP Technologies with our MTS 810 Servo-hydraulic System. Typically fatigue cracking occurs due to cycling from thousands to millions of times at stress levels below what would be considered unsafe for the material. During cycling, the material develops microscopic material flaws leading to formation of microscopic cracks. Once formed, these cracks will continue to grow until they are either identified and repaired or propagate to cause catastrophic failure.

This a nice demonstration, I often use to awareness of the trainees

My 40mm wide MTB wheels have hairline cracks forming at the spoke holes. Yet the wheel feels absolutely rock solid - between now and when I replace the wheels I have to keep a very close eye on these mysterious fissures.

Can u upload the a bigger and detail view of the testing performed?? In this video much less details are visible?? I actually want to Know how to carry a fatigue test on Rectangular bar?
