在高温低循环疲劳试验中,为了不使试样在承受拉压交变循环时失稳,通常采用带圆弧过渡的试样,以保证试样有足够的刚度。高温低循环疲劳试验所采用的试样及有关尺寸如图1所示。
In the high temperature and low cycle fatigue test, in order not to destabilize the specimen under the cyclic tension-compression cycle, specimens with arc transition are usually used to ensure sufficient rigidity of the specimen. High temperature and low cycle fatigue test specimens and the use of the size shown in Figure 1.
