摘要：
The effect of real average strain on the low cycle fatigue life of a SiC particulate reinforced aluminum composite was studied. Pure aluminum was selected as a matrix material for ensuring the similarity of microstructure between the reinforced matrix and the unreinforced material. The low cycle fatigue endurance of the composite was generally lower than that of the unreinforced maximum under whole plastic strain amplitudes. The mechanics of real strain extent and the strain concentration adjacent to reinforcement both contributed to the shorter low-cycle fatigue life of the composite.
