金属的循环加荷在某些情况下引起试样相当大程度的自加热。记录试样在试验时的温度,可以得到大量关于疲劳断裂周期和能量费用的情报。在文献中记述了循环加荷条件下记录旋转试样温度的某些方法,并指出了其缺点:
The cyclic loading of metals causes a considerable degree of self-heating of the sample in some cases. Record the temperature of the specimen during the test, a lot of intelligence about the fatigue fracture cycle and energy costs can be obtained. Some methods of recording the temperature of a rotating sample under cyclic loading conditions are described in the literature and points out its disadvantages:
