Electrochemo-poromechanics of ionic polymer metal composites: identification of the model parameters

Abstract:We propose a procedure to identify the parameters of a model for the multiphysics response of ionic polymer metal composites (IPMCs). Aiming at computational efficiency and accuracy, the procedure combines analytical structural mechanics and fully-coupled electrochemo-poromechanics, additionally resorting to an evolutionary algorithm. Specifically, we consider the finite-deformation electrochemo-poromechanical theory recently developed by our group, which couples the linear momentum balance, the mass balances … Show more
“…85 Fourth, the large number of parameters involved in the response of IL-IPMCs could cause hurdles in the adoption of physically based models in the engineering community. Procedures for the identification of parameters for water-swollen IPMCs 86 shall be extended to IL-IPMCs. Finally, a systematic comparison between the two categories of IL-IPMCs identified should be performed, to characterize the fundamental differences between their responses.…”
