Epaarachchi, Jayantha A. (2005) Effects of static fatigue on the tension-tension fatigue life of glass / polyester composites. In: 4th Australasian Congress on Applied Mechanics (ACAM 2005): Advances in Applied Mechanics, 16-18 Feb 2005, Melbourne, Australia.
The effects of static-fatigue interaction on tension-tension fatigue life of Glass/Polyester composites were investigated using fatigue and static-fatigue experimental data available in the literature. An empirical static-fatigue model was proposed. Predictions from the static-fatigue model and calculation of fatigue life with the static-fatigue interaction show a good agreement with the experimental results. Static-Fatigue interaction has shown a considerable effect on fatigue lives of GFRP composites at intermediate and lower applied stress levels possibly due to a longer exposure to applied loads. At higher load levels approximately greater than 65% of ultimate stress, and higher stress ratios range like 0.7<R<0.9, fatigue lives shown to be closer to material’s static – fatigue limits which is shorter than the expected lifetime by cyclic fatigue.
