Abstract

In this paper, the element-free Galerkin method is employed for evaluating eddy current distribution in ferromagnetic media, whose cross-section is subjected to an imposed time-dependent homothetic transformation and to a time-varying magnetic flux. A step-by-step procedure is used for handling the transient evolution. The extension to nonlinear and hysteretic media is realized adopting the fixed point scheme and the classical Preisach model
