چکیده
|
The dynamic response of an anisotropic multilayer magneto-electro-elastic (mee) plate due to an external excitation is investigated in this work, using the stiffness matrix approach. a parametric study is performed by varying the stacking sequence, polarization direction, boundary conditions, and interlayer thickness. the proposed method yields the numerical estimation of the dispersion curve and the free vibration of the lamb waves for different crystallographic orientations and magneto-electric boundary conditions. it is demonstrated that the anisotropy highly affects the dispersion curve and the non-dimensional frequency, and also decreases the interlayer thickness of the magneto-electro-elastic multilayer and raises the phase velocity of the fundamental symmetric lamb mode vibration. the key outcomes of this research can serve as a reference in the design and analysis of new smart magneto-electro-elastic structures.
