Abstract

An extension on Kirchhoff-Rayleigh theory for inhomogeneous elastic plate is proposed with respect to the covariance of expressions under the coordinate rotation. The covariance is definitely expressed by tensor basis, which also enables to formulate flexural wave according to the weak form framework and to obtain a generalized expression of the boundary condition and the energy flux.
