Bending Test

This servo hydraulic dynamic fatigue test machine is a highly integrated dynamic and static testing system. It can not only conduct high-cycle fatigue, low-cycle fatigue, high-low cycle fatigue, fracture mechanics: fatigue crack growth, fracture toughness, crack growth, KIc, JIc, component strength and durability, thermomechanical fatigue, etc., but also static tension, compression, and bending tests under the control of constant rate, constant strain, and constant stress.

It can be configured according to the user’s specific test requirements, select the host load frame (integrated with the actuator and servo valve installed), hydraulic oil source, DOLI control system (DOLI control system consists of three parts: DOLI system software on computer, digital controller and manual control panel), fixtures and accessories
