铝合金复合材料疲劳过程塑性变形的跟踪测量

The Measurement of All Alloy Composite Plastic Strain in Low Cycle Fatigue

在材料低周疲劳过程中，由检测的应变信号，利用现代谱分析技术处理，得到材料疲劳过程的塑性变形并进行实时跟踪．

The modern signal analysis is used to measure the plastic strain in low cycle fatigue in this paper. The material for investigation is All Alloy Composite. A new method for calculation of plastic strain in line is proposed. 
