New paper on a micromechanical model for the prediction of fatigue damage evolution and fatigue life (S-N curves)

Have you ever though about what make composite materials fail under cyclic loading? In the paper we collect evidence of what is fatigue damage actually is. We combine the collected clues into a conceptual model for fatigue damage in unidirectional composites. Next, we formulate a mathematical micromechanical model. The model can predict the fatigue life of a unidirectional fibre composites from the basic mechanics properties of the fibre, matrix and the fibre/matrix interface.
