Fatigue Lifetime Prediction of Laminated Composites a Review
International Journal of Recent Technology and Engineering (IJRTE), 2020 It is evident that laminated reinforced composite are successfully prolonging the life of composites compared to particle and fiber type of reinforced composites method. The question on how these laminated composites take up the fatigue loading is crucial in order to give sound confident to industry replacing their design from metal to composites based.
