There are two types of beam theories: the first one is the traditional Euler-Bernoulli theory while the second one is Timoshenko beam theory that considers additional effects of shear deformations and rotary inertia. In this investigation, the both theories are utilized to evaluate elastic constants. leading to direct comparisons of the two theories. Also, for a numerical analysis the commercial FEM program. ANSYS 5.3 is employed to conduct modelling of test specimens for a modal analysis, enhancing the understanding of the nature of the FEM analysis and allowing comparisons with experimental results.
