铝合金复合材料恒幅疲劳瞬时损伤研究

The Investigation of Fatigue Damage in Al Alloy Composite

基于局部应变法，在材料的恒幅低周疲劳中，由检测的应变信号，通过谱分析技术处理，得出材料疲劳断裂破坏的临界值。

In this paper a way to determine the material critical crack damage in the low-cycle fatigue by modern signal analysis is presented. With this way we can monitor the crack growh.
