Abstract

A cure-dependent viscoelastic constitutive model is simply derived, and verified by comparing the results predicted by the derived model with the theoretic solution of a rod model and the standard ABAQUS elastic solution of a three-dimensional (3D) cross-ply laminate [0/90]s. A 3D simulation of an AS4/3501-6 composite corner is performed to predict the evolution of the residual stresses and distortion during the entire cure process, and the effect of boundary condition is investigated. The results show that the model for the predictions of the residual stresses and distortion in composite component should include both the curing process and cooling process, and the effects of stress relaxation, chemical shrinkage and thermal deformation should be considered. A proper boundary condition is important for the accuracy of the numerical simulations.
