12th International Conference on Engineering Mathematics and Physics (ICEMP23) 5th - 7th July 2023, Kuala Lumpur, Malaysia Speakers: Assoc. Prof. Dr. Liu Mei Feng Abstract: New governing equation for the transverse vibration of fully coupled thermo-magneto-electro-elastic (TMEE) thin laminates accounting for entropy constitutive equation is derived in this paper. In particular, free vibration for the bi-layered BaTiO3-CoFe2O4 composite and the three-layered laminate made of CoFe2O4 / BaTiO3 stacked on elastic Epoxy are implemented as demonstration examples. Complete constitutive equations regarding the elastic stresses, electric displacements, magnetic fluxes as well as the entropy of the thermodynamic system are revisited, their corresponding alternative forms are further introduced so that Navier elastic equation, the Gauss’ laws in the absence of free charges and currents, and the steady-state heat equation can be applied. Based on the Kirchhoff thin plate theory in accordance with the non-zero out-of-plane field assumptions, bending problem for the transversely isotropic TMEE rectangular plates is investigated, governing equation in terms of the transverse displacement is then presented in a rather compact form. The effective material coefficients for the TMEE laminate are presented and expressed via the volume fraction (vf) of either the piezoelectric phase constituent or the piezomagnetic phase constituent. Natural frequencies of the proposed TMEE coupling thin plates are analytically evaluated, and the effects of different volume fraction on the natural frequency are discussed; in addition, the existence of elastic substrate Epoxy and its effect are further investigated.
