This chapter develops the governing equations of motion for a homogeneous isotropic elastic solid, using the linear three-dimensional theory of elasticity in cylindrical coordinates. At first, classical relationships between stress, strain, and displacement are reviewed and implemented into the dynamic equilibrium equations. The mathematical representations of the linear theory of elasticity derived in this chapter will set the stage for the development of the required governing equations for the possible modes of vibrations in cylindrical structures with any thickness.
