Experimental observations and numerical analysis of fatigue crack development in fiber metal laminates
(English)Manuscript (preprint) (Other academic)
Experimental and numerical studies have been carried out in order to reveal and explain the crack growth behavior of glass fiber reinforced aluminum laminates (GLARE®). Fatigue crack growth tests with center crack tension specimen have been performed. Optical crack growth measurements for surface cracks combined with in situ ultrasonic measurements, to determine the delamination size and shape, have been conducted. Complimentary fatigue induced delamination growth tests have also been performed, and the results from the two experiments have been compared. A 3D linear elastic model has been developed. Comparison between model and experimental results are made, and suggestions for further development in modeling are given.
