Numerical characterization of effective fully coupled thermo-electro-magneto-viscoelastic-plastic response of smart composites

• A micromechanics model was developed for the time-dependent and nonlinear multiphysics responses of smart composites
• All calculations were accomplished in time domain.
• This model possesses the advantages of geometrical flexibility and performing simulation without relying on boundary conditions.
• The accuracy and efficiency of the proposed model have been verified by ABAQUS finite element models.

The focus of the present paper is to construct a general purpose micromechanics model to predict the effective fully coupled time-dependent and non-linear multiphysics responses of smart composites. The present model is established on the basis of the variational asymptotic method and implemented using the finite element method. In light of the time-dependent and non-linear characteristics of composites, an incremental procedure in conjunction with an instantaneous tangential electromagnetomechanical matrix of composites was established. The accuracy of the proposed model was verified through the comparison with ABAQUS results. Finally, a numerical example was employed to demonstrate the capability of the proposed model.
