Kinematics of normal modes in elastic layer for some wavenumbers investigation based on n-th order three-dimensional shells’ theory

Abstract:

Normal modes in an isotropic elastic layer are considered using an approximated three-dimensional shells’ theory of N’th order and it’s convergence to the Rayleigh-Lamb problem’s solution is investigated at some nonzero wavenumbers. Normal mode frequencies and shapes convergence is considered.
