This chapter considers the free and forced transverse vibration of beams. It derives the equations of motion of a beam according to the Euler〣ernoulli, Rayleigh, and Timoshenko theories. The Euler〣ernoulli theory neglects the effects of rotary inertia and shear deformation and is applicable to...

Free vibrationThe flexural vibrations of cracked micro- and nanobeams in the presence of surface effects are studied. The cracked-beam model is set up by dividing the classical cracked beam element into two segments connected by a rotational spring located at the cracked section. This model ...

This paper presents a semianalytical method to analyze the natural frequencies and mode shapes of an undamped double-beam system, which is composed of two beams joined by a uniformly distributed connecting elastic layer, with arbitrary beam mass, beam flexural rigidity, and arbitrary boundary conditio...
transverse vibration of nanobeams, of which some are the fully clamped beams according to their boundary constraints.In fact.fully clamped condition is one of the most important boundary types and it is easily to be seen in NEMS.However.in recent years, the literature regarding the vibration ...
This paper is concerned with the transverse vibration of uniform Euler–Bernoulli beams under linearly varying fully tensile, partly tensile or fully compressive axial force distribution. The system parameters are the constant part of the axial force and the constant of proportionality of the varying ...
