Design, Modeling and Computation of Active Thin Films

Abstract

A new theory and numerical methods for the mechanical behavior of thin films were developed. The theory was applied to shape memory and ferromagnetic shape memory materials. This suggested several new designs for microactuators. One of these, a microvalve, was numerically simulated. It showed a reversible motion induced by temperature change and a nearly square hysteresis loop (valve opening vs. temperature). In addition, the deformation and transformation of a thin film by indentation and the disappearance of the indentation by heating and reverse phase transformation were numerically simulated.
