Abstract: Based on the symplectic theory in applied mechanics, some characteristic theories, such as the symplectic Gramme-Schmidt orthogonal algorithm, the independence between symplectic eigensolutions, precise integration method for the problem with two end boundary conditions, etc. were employed to analyze the energy band structure of Timoshenko beam and the wave scattering in the beam which was connected with a rigid scatterer.
