Abstract: A virtual manufacturing environment that provides modules for predicting the process-induced residual stresses in polymeric composite materials has recently gone through extensive testing by the authors. The use of polymeric composite materials in Department of Defense materiel developments has made it increasingly important to predict the service life and the mechanical responses of such structures. Process-induced behavior plays a critical role in the accurate modeling of mechanical responses. Predicting process-induced residual stresses of composite material structures requires the coupling of resin infusion, heat transfer, and multiscale thermal residual stress models. The complexity of modeling the process-induced effects requires the use of modern software engineering techniques
