Structural part fatigue testing machine

It is mainly used for tensile, compression, fatigue, low-cycle fatigue, crack propagation, fracture mechanics, physical testing and simulation testing of metallic materials and non-metallic materials, components, structural parts, standard parts, especially new materials such as super-strength steel, titanium alloys and reinforced synthetic fibers, etc. to determine their fatigue performance parameters, fatigue life, cyclic elastic modulus, and fatigue crack growth rate.
