The purpose of the paper is to present a class of reduced models borrowed from structural mechanics aimed at specifically describing swelling-induced bending deformations in a gel bar. A distinct bending pattern to be confirmed by an appropriate experimental setup is evidenced through the analysis of a plane stress-diffusion model. Moreover, a further reduced 1D stress-diffusion model driven by an integro-differential equation is derived. In particular, it is shown that there exists a range of the material parameters where the standard 10 diffusion equation holds. (C) 2012 Elsevier Ltd. All rights reserved.

Abstract
The purpose of the paper is to present a class of reduced models borrowed from structural mechanics aimed at specifically describing swelling-induced bending deformations in a gel bar. A distinct bending pattern to be confirmed by an appropriate experimental setup is evidenced through the analysis of a plane stress-diffusion model. Moreover, a further reduced 1D stress-diffusion model driven by an integro-differential equation is derived. In particular, it is shown that there exists a range of the material parameters where the standard 10 diffusion equation holds. (C) 2012 Elsevier Ltd. All rights reserved.File in questo prodotto:
