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
The professional technical team proposes Huanye's analysis opinions and solutions to protect customers' product design, production and periodic operation and maintenance in response to customers' requirements to improve product reliability and reduce the risk of failure such as fatigue and fracture.
