Experimental researches on magneto-thermo-mechanical characterization of Terfenol-D

Experimental researches on magneto-thermo-mechanical characterization of Terfenol-D Abstract The coupling effects of axial pre-stress, temperature and magnetic field on magnetostrictive strain and magnetization as well as Young’s modulus of a Terfenol-D (Tb0.3Dy0.7Fe1.93) rod are tested to give a good understanding of magneto-thermal-mechanical characteristics of giant magnetostrictive materials. Results show that magneto-thermo-mechanical coupling of giant magnetostrictive materials is very strong; and the influences of pre-stress and temperature on magnetostrictive strain and Young’s modulus vary with the intensity of magnetic field. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png "Acta Mechanica Solida Sinica" Springer Journals

Abstract

Abstract The coupling effects of axial pre-stress, temperature and magnetic field on magnetostrictive strain and magnetization as well as Young’s modulus of a Terfenol-D (Tb0.3Dy0.7Fe1.93) rod are tested to give a good understanding of magneto-thermal-mechanical characteristics of giant magnetostrictive materials. Results show that magneto-thermo-mechanical coupling of giant magnetostrictive materials is very strong; and the influences of pre-stress and temperature on magnetostrictive strain and Young’s modulus vary with the intensity of magnetic field.
