Fatigue and life analysis
· Safeguard product design, production and periodic operation and maintenance

Service background
Fatigue failure is one of the main reasons for the failure of mechanical parts. Fatigue fracture is different from fracture under static force. Whether it is brittle or ductile material, fatigue fracture occurs suddenly. There is no obvious sign of plastic deformation in advance. It is difficult to detect in advance. It is also a low-stress brittle fracture, so it is very dangerous.

Fatigue and life analysis service project
