Stiffness reduction model for composite materials under cyclic loading - identification of model coefficients
Original language description
The use of fiber reinforced composites for structural components requires reliable knowledge of their damage and failure behavior. Damage mechanisms of fiber composites subjected to static loading are satisfactory described and the determination of safety margins is usually feasible. In the case of composite structures subjected to cyclic loading the situation is rather complicated. In comparison with metals fatigue behavior of composites is affected by many damage modes dependent on stress level, loading frequency, number of cycles and others. Among the outer signs of fatigue damage particularly important for engineers can be included reduction of stiffness and strength. The main goal of this paper is to describe proposed stiffness reduction model with the focus on the identification of model coefficients on the basis of unidirectional tensile experiments.
