Three-dimensional vibration of rectangular Y-cut crystal plate has been investigated in this paper. The three displacements components of plate are expanded in three directions by series of Chebyshev polynomial multiplied by the boundary function R which makes expansions satisfy the essential boundary conditions along the edges. The eigenvalue matrix for natural vibration frequencies is obtained for rectangular crystal plate by Ritz method and then solved by computer program.
