Magnetoelastic Relationships for Large Diameter Terfenol

Abstract

This paper discusses the proper form of the piezomagnetic matrix appropriate for Terfenol-D using material that is commercially available today. The full piezomagnetic matrix consists of the compliance matrix, the piezomagnetic matrix and the permeability matrix. The general matrix has 45 independent constants, however these can be reduced to 5 independent constants by applying symmetry appropriate Terfenol-D driver material. We also briefly discuss methods of measuring these constants.
