Crack Growth Fatigue Test and Crack-Tip Opening Displacement Test Dynamic Testing System
static hydraulic universal testing machine
Application:
It is mainly used to detect the static and dynamic mechanical properties of metal and non-metal materials. It can realize mechanical tests such as tension, compression, tension-tension, compression-compression and tension-compression, as well as high-cycle fatigue, low-cycle fatigue, crack growth, fracture toughness and other tests, and realize various waveform outputs such as sine wave, triangle wave, square wave, etc.
Features:
1.The crossbeam is placed on top and the actuator is placed on the bottom to form a closed frame structure. The frame has high rigidity, no reverse clearance and good stability.
2.The actuator adopts a double-acting cylinder design, with reasonable space design and easy operation.
3.The lifting, locking and sample clamping of the mobile crossbeam are all operated by buttons, which is flexible and convenient.
