摘要
Recently, the inconsistencies are pointed out by previous authors for the problem of finding the strains, stresses and energy densities observed in isotropic elastic magnetostrictive materials that are in the form of thin films deposited on non-magnetic substrates. We discuss the reason of such inconsistencies that the total normal stresses should be the sum of the stresses caused by the external mechanical force and magnetic field. We show that such a situation can be realized in many of the current models used to make predictions for magnetostrictive structures and the inconsistencies can be explained.
