title = "Plane-strain deformations of ionic polymer-metal composites",
abstract = "The technology of ionic polymer-metal composites (IPMCs) has steadily seen remarkable advancements, but their underlying physics is still elusive. The hypothesis of rigid cross-section is often put forward in IPMC modeling, within structural beam-or plate-like theories. We assess the validity of this hypothesis through the two-dimensional study of multiaxial deformation, based on a thermodynamically-consistent model of IPMC actuation. Our analytical solution is validated through finite element simulations via user-defined elements in Abaqus. Our work demonstrates a rich and complex strain deformation pattern along with a counterintuitive dependence on the Poisson's ratio.",
