Fatigue Characteristic of Metal Rubber Material

Fatigue test of metal rubber specimen was carried out at high and low temperature and the form of fatigue rupture and character of disk specimen was analyzed.The lattice structure and cavity defect of the material was observed under SEM,and the damaging parameter with cyclic periodic time was concluded qualitatively.Through analysis of the fracture of the metal wire,the fatigue mechanism and influencing factors had been studied.According to these influencing factors,some technique paths have been brought forward to improve the fatigue strength of metal rubber material.
