A method is presented to obtain accurate estimations of the natural frequencies of nonuniform Euler-Bernoulli beams (the method can deal easily with all possible combinations of classical boundary conditions, including rotating and supporting end springs). The method is based on a repeated finite di
In the paper an asymptotic formula has been developed to correct the discretization error for the finite element predicted natural frequencies of membrane transverse vibration problems. The general idea behind deriving this asymptotic formula is that, when the finite element size approaches zero, a
