Probabilistic Simulation for Combined Cyclic Fatigue in Composites

Abstract:

The combined cyclic fatigue is computationally simulated by a judicious combination of three independent computational modules: composite mechanics, a multi-factor equation module (MFIM) and probabilistic algorithm (FPI). The inputs to each module are constituent material properties, processing variables, loading and environmental conditions and probabilistic variables. The composite fatigue is simulated by considering an inplane loaded-component in a structure which is subjected to fatigue because of cyclic loading. Typical results show that the low probability fatigue cycle is about 50 percent of the corresponding static value.
