In the present paper, a stochastic approach is developed for modelling and analysis of fatigue response test data of composite laminates. The damage development is identified and quantified through the correlation analysis. The stochastic analysis results are related to the microstructure observations. The fatigue behaviour of AS4/3501-6 Graphite Epoxy cross ply lay up [0/90]_(4s) with 60percent volume fraction is described through this stochastic approach.
