Abstract

A variational statement of the nonlinear boundary value problem of magneto-mechanical interactions in magnetostrictive materials is presented. Some of the complexities arising out of the nature of these interactions are pointed out. A finite element code developed on the basis of a linearized version of the above variational statement is used to model the behavior of an idealized magnetostrictive actuator. The strong influence of coupling constants on the induced magnetic field is demonstrated through our coupled finite element analysis. Errors that are possible in uncoupled analyses are illustrated and the need for fully coupled analyses of general two or three dimensional actuator configurations is brought out.
