“…One approach to modelling is to incorporate the heterogeneity of the material within a multi-scale piezomagnetic framework. The different phases at the lower level of observation are modelled explicitly and homogenisation principles may be applied to derive effective properties [1,2,18,27,28]. This requires the identification of a suitable Representative Volume Element at the lower scale of observation, after which Fourier transforms [1,2] or Eshelby solutions [18,27,28] may be used to quantify the relevant effective properties.…”
