Magnetostriction is the magnetisation-induced strain in ferromagnetic materials. It highly depends on mechanical stress. Stress state in electromagnetic devices is usually multiaxial and its effect on magnetostrictive properties is not easily predicted. In this paper, an original three-parameter analytical model for the stress-dependent magnetostriction strain of ferromagnetic materials is proposed. It is based on a simplified energetic description of magneto-elastic behaviour. It follows a similar method previously adopted for the description of the effect of stress on the magnetic permeability of magnetic materials. It is applied for the first time to the magnetostriction behaviour and results in a simple formula to express the effect of multiaxial magneto-mechanical loadings on the magnetostriction strain. The approach also naturally includes the description of the so-called ΔE effect. The analytical formula is derived in the paper. It shows very satisfying agreement with experimental results on iron–cobalt alloy and pure iron specimen.

“…Magnetic and mechanical behaviours are strongly coupled [1]. Magnetisation is very sensitive to the application of stress, leading to significant effects on the performance of electromagnetic devices [2][3][4]. Conversely, the magnetisation process is associated with a mechanical deformation called magnetostriction.…”

“…On the same lines, a combined stress and electromagnetic 2-D FE analysis was carried out by Yamazaki and Kato (2014) and Yamazaki and Takeuchi (2017), and the effect of stress was included in a two-component core loss formula. A 3-D FE analysis-based magneto-mechanical model was presented in Ebrahimi et al (2016) and the effect of stress was considered in the hysteresis loss coefficient.…”

Giant magnetostrictive materials such as Terfenol-D and Galfenol are used to design actuators and sensors, converting magnetic input into a mechanical response, or conversely, mechanical input into a magnetic signal. Under standard operating conditions, these materials are subjected to stress. It is therefore important to be able to measure, understand and describe their magneto-mechanical behaviour under stress. In this paper, a comprehensive characterisation of the anhysteretic magneto-mechanical behaviour of Terfenol-D was performed. An energy-based multiscale approach was applied to model this behaviour. Finally, it was shown that the strain behaviour of Terfenol-D can be satisfactorily described using an analytical model derived from the full multiscale approach.
