title = "Fatigue of glass fibre reinforced polymers for ocean energy",
abstract = "A combined experimental and computational study on the fatigue of glass-fibre reinforced polymers (GFRP) is presented, with particular emphasis on the effects of water saturation, for use in ocean energy structures. The experimental characterisation consisted (i) of immersion-aging of test specimens for a period of up to two years, using a moderate accelerated aging technique, designed to simulate longer-term seawater exposure of the material, and (ii) fatigue testing of aged and unaged specimens in immersed and non-immersed conditions, with emphasis on identification of fatigue damage evolution. The computational methodology incorporates the development of a multiaxial fatigue damage user material subroutine, based on the static Puck approach, adapted for fatigue by combining (i) fatigue-induced fibre strength and modulus degradation, (ii) irrecoverable cyclic strain effects and (iii) inter-fibre fatigue. Finally the impact of water saturation on the fatigue life of a tidal turbine blade is assessed using a fatigue life model.",
