Abstract

In this paper, we propose a novel modeling framework to study quasi-static large deformations and electrochemistry of ionic polymer metal composites (IPMCs). The chemoelectromechanical constitutive behavior is obtained from a Helmholtz free energy density, which accounts for mechanical stretching, ion mixing, and electric polarization. The framework is specialized to plane bending of thin IPMCs through a structural model, where the bending moment of the IPMC is computed from a one-dimensional modified Poisson-Nernst-Planck system. For small static deformations, we establish a semianalytical solution based on the method of matched asymptotic expansions, which we ultimately use to elucidate the physics of IPMC sensing and actuation.
