Abstract / Description of output

Typical short fiber composites components have a different statistical distribution of orientation of fibers at different points leading to different material mechanical and fatigue behavior at different points. For a component-sized calculation, each point in the FE model is the center of a Representative Volume Element (RVE) where the static and fatigue properties must be known. A hybrid multi-scale method of predicting the SN curve for every point in a short fiber composite is presented. This method is based on the assumption that the stiffness degradation curves of similar RVE must be similar. An extensive test program was undertaken to study the fatigue behavior of short fiber composites and validate the concept of the Master SN curve. Master SN curve was found to be in excellent match with the experimental results.
