In this paper, a stiffness-based model is initially assessed for fatigue damage analysis of composite structures. The model is evaluated with three sets of experimental data. A residual strength model is coupled to the choice model and a modified model is developed. Numerical results show that the modified model leads to improvement of predicted fatigue lives for two-stage loadings. To determine the variations of the predicted fatigue lives, probabilistic assessment is done by Monte-Carlo simulation. Normal distribution is fitted with good agreement to the histogram and empirical CDF of the numerical life predictions.
