Biaxial stress effects on the magnetic properties of pure iron

Setup to test biaxial stress effect on magnetomechanic coupling

“…This model is in good agreement with experimental results reported by Pearson et al, 3 but is criticized in Ref. 4 for it does not account for the 3D tensorial nature of stress.…”

Energetical and multiscale approaches for the definition of an equivalent stress for magneto-elastic couplings

“…The results of Pearson et al [27] and Maurel et al [33] are accessible and can be reinterpreted. Pearson et al obtained maps of the relative variation of the coercive field (%) in the biaxial stress plane for a pure iron.…”

“…This equivalent stress can be implemented into a macroscopic uniaxial magneto-mechanical model. This method has been followed by several authors in the past years [24][25][26][27]. These equivalent stresses have been compared recently [29], we only briefly recall their definition hereafter.…”

“…Pearson et al [27], under similar assumptions and using the notations of Schneider and Richardson's proposal, make use of a function gðrÞ (Eq. (24)).…”

“…The second step is to implement this scalar value into a uniaxial macroscopic magneto-mechanical model. Some authors proposed such an approach in the past years [24][25][26][27]. It is shown that in many cases these proposals are not fully satisfactory.…”
