Abstract:Under dynamic loading conditions, damage in a plain weave Carbon Fiber Reinforced Polymer (CFRP) composite is a complex and multiscale process especially in the presence of a manufacturing flaw. In this context, this paper investigates the impact of an inserted flaw on the damage scenario and stiffness degradation over fatigue life. To achieve this objective, a full three-dimensional Finite Element Model (FEM) is developed to evaluate the stress distribution induced by the local defect. Fatigue tests are then … Show more
