Constant amplitude fatigue testing at LSP Technologies with our MTS 810 Servo-hydraulic System. Fatigue cracking typically 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.

Laser peening enhances material resistance to crack initiation and propagation, and can even be applied to arrest the growth of existing cracks. Contact LSPT to learn more.
