Abstract
Fatigue failure in composite materials can be successfully modeled and predicted by monitoring irreversible gains in entropy. Permanent degradations in composites are marked by irreversible processes that are characterized by increases in entropy. By measuring changes in entropy, one can model and predict the deterioration and failure of composites. The technique may be used to predict the deterioration and failure of composites under essentially any type of loading—constant, variable, bending, torsion, tension, compression, or other.
