We aim at coupling the theory of swelling, describing the effects of solvent uptake in polymeric solids, with that of growing, describing the change of the relaxed state in a continuum body. Basing on the hypotheses underlying the two theories, and using some key principles of continuum mechanics, we develop a chemo-mechanical model which describes the combined effects of swelling and growing in solids.
