Determination of material constants of magnetostrictive materials / Linchevskyi I. // International Scientific and Practical Conference «Scientists and methods of using modern technologies, Melbourne, Australia, May 30 – June 2, 2023. – 2023, Melbourne. – P. 364-370.https://ela.kpi.ua/handle/123456789/56742A mathematical model of a toroidal inductor with a flat ring core made of a polycrystalline magnetostrictive ferromagnet capable of oscillations was developed, as well as a method of measuring the material constants of a polycrystalline ferromagnetic core based on the resonance frequencies of radial oscillations of a ring placed in a toroidal coil. Material constants are understood as a set of the following quantities: components of the tensor of the modulus of elasticity of a demagnetized ferromagnet, components of the tensor of magnetostrictive constants, and components of the tensor of the magnetic permeability of a ferromagnet.enmagnetostrictionmagnetomechanical resonancematerial constantsArticleP. 364-370https://doi.org/10.46299/ISG.2023.1.21
