Lamb waves in functionally graded plates with transverse inhomogeneity
- 43 Downloads
Propagation of harmonic Lamb waves in plates made of functionally graded materials with transverse inhomogeneity is studied by the modified Cauchy six-dimensional formalism. For arbitrary transverse inhomogeneity, a closed-form dispersion equation is derived. Dispersion relations for materials with different kinds of inhomogeneity are obtained and compared.
