Abstract
A numerical technique is proposed to simulate the dynamic electro-mechanical properties of ionic polymer-metal composites (IPMC) using a finite element program ANSYS. The Runger-Kutta method is employed to solve the partial differential equation of ionic density which was incorporated into ANSYS by coding user-defined subroutines, and the mechanical bending resulting from the water molecules redistribution is simulated by building equivalent thermal expansion model. Using the proposed method, the ion movement and the electro-mechanical deformation behavior were predicted. Compared with those available open literatures, the numerical results show the validity of the present method.
