報告摘要：
A network of polymers can imbibe a large quantity of solvent molecules and swell, resulting in a gel. The swelling process can be markedly influenced by a mechanical load and geometric constraint. We formulate a theory of the coupled mass transport and large deformation via a variational approach. A gel can undergo large deformation of two modes. The first mode results from the fast process of local rearrangement of molecules, allowing the gel to change shape but not volume. The second mode results from the slow process of long-range migration of the small molecules, allowing the gel to change both shape and volume. A finite-element package is further implemented based on the equilibrium theory of polymeric gels.
