Servo Hydraulic Fatigue and Fracture Testing Machine

 

 

The test system can not only perform dynamic high- and low-cycle fatigue tests, program-controlled fatigue tests, but also static tests under constant rate, constant strain, and constant stress control, and various conventional mechanical performance tests. Fracture mechanics tests can also be performed, and fatigue life, crack propagation, fracture toughness performance testing of materials or components in a broad range, safety evaluation of actual specimens, and working condition simulations can be performed. By replacing the attachments, fatigue and static mechanical performance tests of various structural parts, components and assemblies can also be carried out. Therefore, it has the incomparable advantages of any other type of testing machine, and is the most respected material testing equipment in the international fatigue mechanics research field.
