Abstract

Free vibration analysis of higher-order shear deformation beam resting on one- and two-parameter elastic
foundation is studied using differential transform method (DTM) as a part of a calculation procedure. First,
the governing differential equations of beam are derived in a general form considering the shear-free
boundary conditions (zero shear stress conditions at the top and bottom of a beam). Using DTM the derived
equations governing beams, followed by higher-order shear deformation model, Timoshenko model and
Bernoulli-Euler model are transformed to algebraic forms and a set of recurrence formulae is then derived.
Upon imposing the boundary conditions of the beam at hand, a set of algebraic equations are obtained and
expressed in matrix form. Finally, the transverse natural frequencies of the beam are calculated through an
iterative procedure. Several numerical examples have been carried out to demonstrate the competency of
the present method and the results obtained by DTM are in good agreement with those in the literature.
Afterward, the free vibration of beams followed up by different models (i.e. Bernoulli-Euler, Timoshenko
and different higher-order models) are taken into consideration.
