Fatigue failure model for fiber bundles

In this report, a theoretical model of fatigue failure for fiber bundles with surface flaw is proposed based on the classical concept of crack growth behavior. Maximum surface flaw on each fiber in the bundle is taken as source of crack propagation. Modeling is proceeded from stress redistribution...
