Abstract

The magnetomechanical coupling coefficient, k33, has been modeled as a function of the elastic modulus of the matrix, Em , of composite magnetostrictive materials. Measurements of k33 have been performed by a three-parameter technique on glass-matrix Terfenol-D composites fabricated from powders heated to 700°C in an inert atmosphere under the application of a 1-3 kN force. It is concluded that there is a value of Em for optimum magnetomechanical performance which is dependent on the volume fraction, Vf. The optimum value of Em is close to, but less than, the elastic modulus of the magnetostrictive material
