WebNov 1, 2024 · With the model proposed in this work it is possible to take into account the effects of elevated temperatures on the fatigue life of rubber and give a more accurate fatigue life prediction. Since the influences of elevated temperatures appeared to be very distinct, more experiments have to be performed to provide a complete insight into the ... WebEffect of rail-pad stiffness and concrete slab thickness on fatigue life index of concrete slab in different locations (a) mid-point (b) end-point. It is due to the fact that as the slab thickness increases, the tensile stress at the bottom surface of slab decreases and consequently, the fatigue life increases.
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.
