Deformation of corrugated hydrogel panel subject to chemo-mechanical coupled loading

•Chemically coupled Young’s modulus and Poisson’s ratio are theoretically formulated for polymeric hydrogels.•Elastic constants coupling chemical influences may provide comprehensive guide for analysis and design of soft structures.•Exact bending solution is derived for corrugated hydrogel panels in the framework of symplectic elasticity.•A theoretical platform is presented to simulate deformation of soft plate and shell subject to chemo-mechanical stimuli.
