Abstract: For the sake of evaluating the applicability of various constitutive models, a three-dimensional numerical model was constructed to predict the residual stresses/strains and process-induced deformations of composite structures. The model consisted of thermo-chemical analysis mo-dule and thermo-mechanical analysis module, taking thermo-chemical coupling, anisotropy of material properties, chemical shrinkage and viscoelasticity into consideration. Three typical constitutive models of linear elasticity, viscoelasticity and path-dependent were employed to predict the residual stresses/strains and deformations. Furthermore, comparison of simulated results and test results were carried out to verify the validity of the constructed numerical model, and emphasis was put on the study of the applicability of various constitutive models. According to the results, the viscoelastic constitutive model performed best, presenting favorable predicted results of residual stresses/strains and deformations. The path-dependent constitutive model held slightly worse performance than the viscoelastic one, showing encouraging predicted results of resi-dual strains and deformations, nevertheless, unsatisfactory predicted results of residual stresses. The linear elastic constitutive model exhibited the worst performance, achieving accepted predicted result of the residual strains and deformations for only thinner composite structures.
