Mechanical analysis on maximum stress and deflection of an ionic polymer metal composite based fixed-ended beam by finite element method using Nernst-Planck equation

As a new smart material, ionic polymer metal composites, or in short IPMCs, are typically fabricated by coating noble metals such as gold, platinum, and palladium on each other sides of membrane-based on perfluorinated materials such as Nafion and Flemion. These composites can bend significantly by applying a low amount of voltage. Nowadays, there are several methods to fabricate ionic polymer metal composites, including chemical-physical and chemical-chemical ways. we investigate on maximum deflection and stress of an ionic polymer-metal composite as a fixed-fixed beam by finite element method considering Nernst Planck equation. by applying voltage 3.3 V, considering the method, the analysis, and diagrams show that the maximum stress is 2.21×1012 (N/m2). and the maximum deflection is 0.5 mm
