Magneto-electro-mechanical bending analysis of three-layered exponentially graded microplate with piezomagnetic face-sheets resting on Pasternak's foundation via MCST

ABSTRACT

The present work is devoted to the bending behavior of elastic three-layered microplate with exponentially graded core and piezomagnetic face-sheets using the modified couple stress theory (MCST). The micro piezomagnetic layers are subjected to electric and magnetic potentials and the model is resting on Pasternak's foundation. To capture size-dependency for a micro sized rectangular microplate, the MCST is used. Numerical investigation of this problem is surveyed for effect of significant parameters of microplate such as micro length scale parameter, in-homogenous index, electric and magnetic potentials, geometrical characteristics and parameters of foundation on results of problem.
