An investigation on fatigue life evaluation and crack initiation of Al-GFRP bonded lap joints under four-point bending - ScienceDirect
In this paper, fatigue life and crack initiation of aluminum-GFRP bonded lap joints are investigated under four-point bending loading. For this purpose, a new fixture was designed and constructed. Fatigue loads vs. number of cycles to failure (L-N) were obtained so that the influence of various load ratios on L-N were examined. Furthuremore, the load amplitude vs. number of cycle curves were investigated. In addition, the load amplitude vs. mean load curve was obtained at 100,000 cycles.
