Abstract

Analysis of Wave propagation in plates with sinusoidal boundaries has been considered in this paper. Guided elastic wave in a two-dimensional periodically corrugated plate is studied analytically. The plate material is considered as homogeneous, isotropic and linearly elastic. In a periodically corrugated wave-guide all possible spectral order of wave numbers are considered. The dispersion equation is obtained by applying the traction free boundary conditions. Solution of the dispersion equation includes both symmetric and anti-symmetric mode. Non-propagating 'stop bands' and propagating 'pass bands' are investigated.
