Lamb waves in functionally graded magnetoelectric microplates with different boundary conditions (Q6074798)

The authors consider propagation of Lamb waves in a functionally graded magnetoelectric microplate using the Legendre polynomials series for time harmonic P and SV wave couple. The problem is reduced to an algebraic system written in the form of a matrix eigenvalue problem. The eigenvalues and eigenvectors are numerically evaluated to calculate displacement, stress, electric and magnetic distribution. A comparison to earlier results is made to test correctness. The effects of change of magnetoelectric boundary conditions and couple stress are presented graphically in a number of situations.
