Numerical/phenomenological model for fatigue life prediction of hybrid laminates

In this article, the fatigue stress-cycle (S-N) curves of carbon fiber reinforced polymer (CFRP) and glass fiber reinforced polymer (GFRP) were investigated. Experimental fatigue tests were performed on unidirectional specimens and the S-N curves for GFRP and CFRP materials were determined. Obtained...

Description
Summary:In this article, the fatigue stress-cycle (S-N) curves of carbon fiber reinforced polymer (CFRP) and glass fiber reinforced polymer (GFRP) were investigated. Experimental fatigue tests were performed on unidirectional specimens and the S-N curves for GFRP and CFRP materials were determined. Obtained S-N curves were next described by phenomenological model (PM) based on mathematical function containing convexity and concavity ranges of stress-cycle curve. Based on the PM and numerical static analyses performed in ABAQUS/Standard on hybrid glass-carbon fiber reinforced polymer, the fatigue S-N curve was predicted for this material. Numerical/phenomenological model predictions were validated by experimental tests, where good agreement was obtained in the field of static tensile strength, shape of S-N curve and infinite fatigue life.
