>>>>高频振动疲劳试验法

常规疲劳试验中交变载荷的频率一般低于200Hz,无法精确测得一些零件在高频环境状态下的疲劳损伤。高频振动试验利用试验器材产生含有循环载荷频率为1000Hz乐投英超左右特性的交变惯性力作用于疲劳试样上,可以满足在高频、低幅、高循环环境条件下服役金属材料的疲劳性能研究。

>>>>超声法疲劳试验

超声法疲劳试验是一种加速共振式的疲劳试验方法,其测试频率(20kHz)远远超过常规疲劳测试频率(小于200Hz乐投英超)。超声疲劳试验可以在不同载荷特征、不同环境和温度等条件下进行,为疲劳研究提供了一个很好的手段。超声疲劳试验一般用于超高周疲劳试验,主要针对10^9以上周次疲劳试验。高周疲劳时,材料宏观上主要表现为弹性的,所以在损伤本构关系中采用应力、应变等参量的弹性关系处理,而不涉及微塑性。
