Nonlinear dynamic model with multi-fields coupling effects for giant magnetostrictive actuators
International Journal of Solids and Structures, 2013 AbstractThis paper addresses the modeling of complex hysteresis behavior for giant magnetostrictive actuator system under magnetically unbiased conditions. The hysteresis behavior is modeled by establishing a novel nonlinear dynamic model with multi-fields coupling effects, in which both the eddy current effects and the change of stress are considered.

A multi-field coupling model of gas flow in fractured coal seam [PDF]
Advances in Geo-Energy Research, 2021 The structure of fractures and pores has a dominant impact on the heat transfer-seepage-deformation process of a coal seam. Previous models have primarily used the cubic permeability model to characterize coal seam permeability properties. In this study, we developed a new multi-field coupling model, which includes fracture and pore structure, coal seam
