| Summary: | The application of multilayered hydrogel capsules in biomedical engineering has stimulated much interest in the mechanics of soft matter. Based on second-order elasticity theory, this paper presents analytical solutions for a spherically symmetric bilayered hydrogel subjected to a constant dilatation. The results show that: (1) elastic nonlinearity and inhomogeneity play a crucial role in the mechanical state, (2) a wide range of mechanical states can be designed for specific applications by manipulating the layer elasticity and interface position, and (3) the displacement and stresses can be characterized by a reduced set of eight geometric–elastic constants. |
