WebSep 20, 2024 · The fatigue phenomenon widely exists in rubber products, such as tires, seals, dampers and conveyor belts, which are usually exposed to dynamic stress. Therefore, exploring the fatigue damage mechanism of rubber composites has great significance in improving the service life of their products. WebIn silicone materials, mechanical fatigue is defined as a progressive weakening of their physical properties as a result of a slow crack growth during the application of dynamic loads or deformations. The gradual reduction in stiffness is the most visible consequence of this. Various phenomena in the atomic and molecular levels occur during ...
WebRepeated deformation of rubber cylinders in compression causes cracks to initiate at tensile stress concentrations (eg. bond edges). The cracks grow to remove the rubber which at maximum deformation bulges outside the original profile of the cylinder. The results are analysed in terms of fracture mechanics. The tearing energy, T is substantially … WebMar 12, 2024 · Stretching fatigue tests were performed on the P0 and P3.4 electrodes. Figure 5c,d shows the resistance change as a result of repeating the 30% strain stretching 1000 times. The dynamic fatigue test results revealed that the stretchability of the snake-skin electrode was much better and more stable than that of the conventional electrode.
