Electro-hydraulic servo dynamic fatigue testing machine

Termék bevezetése:

Electro-hydraulic servo dynamic and static fatigue testing machine （hereinafter referred to as the test machine） is mainly used for metal materials and non-metal materials, components, structural parts, standard parts, especially new materials such as ultra-strength steel, titanium alloy and reinforced synthetic fiber and other materials tensile, compression, fatigue, low cycle fatigue, crack growth, fracture mechanics test. The fatigue performance parameters, fatigue life, cyclic elastic modulus and fatigue crack growth rate were measured by symmetric cyclic and asymmetric fluctuating and alternating load cycle fatigue tests.
