Abstract
This paper presents an efficient method for solving free vibration problems for an Euler-Bernoulli beam under various supporting conditions. The method is based on the implementation of the sixth-order compact finite difference method (CFDM) for discretizing the governing differential equation to obtain the natural frequencies of beam corresponding to two commonly used boundary conditions namely simply supported-simply supported and clamped-free. A very good agreement is found between the natural frequencies obtained using the sixth-order compact finite difference scheme and exact natural frequencies, which confirms the validity of the present sixth-order discretization.
