Fatigue test room
 

☆ Functional introduction
     Due to the accumulation and development of internal defects, the materials will deteriorate gradually ,thus cause the fatigue crack initiation and propagation and fracture of materials,whichmay lead to disastrous accidents. The fatigue testing lab is able to determine the fatigue property , fracture toughness and crack propagation rate. It can also determine the yield point, specified non-proportional elongation stress, tensile strength, Poisson ratio, true stress, and true strain of materials Rapidly.
