In order to study on fatigue life performance of the Al-Li alloy and fiber metal laminates (2/1 laminates and 3/2 laminates of glass fiber reinforced Al-Li alloy) under different loading modes, these materials are subjected to fatigue life test. Each type of the materials is applied to cyclic stress, which has different cycle characteristics (constant amplitude with the stress ratio 0.06, unimodal tensile overload and unimodal compressive overload). Nine kinds of test data on stress life are obtained and P-S-N curve of each material is fitted using the principle of sample polymerization. In addition, the differences of the S-N curve with the same material in different loading modes and different materials in the same loading mode are compared with each other. The results show that all of the three kinds of materials show the effect of overload retardation under tensile overload, Al-Li alloy material exhibits accelerated destruction effect and laminate materials exhibit a delayed effect under compressive overload. The pros and cons of fatigue performance between different structural laminates have a relationship with remote stress.
Key words： fiber metal laminates; fatigue life; fatigue test; cyclic stress; overloads
