One of the most common tasks in vibration analysis is the determination of the steady-state response of a system to harmonic forcing. This is also true in AC electrical circuit analysis. The most common case encountered in vibration engineering is that of the forced underdamped system. In this case, the transient portion of the response vanishes exponentially as e−ζωt, where ζ is the so-called ...
In this paper, a numerical solution procedure is presented for the free and forced vibration of a piezoelectric nanowire under thermo-electro-mechanical loads based on the nonlocal elasticity theory within the framework of Timoshenko beam theory. The influences of surface piezoelectricity, surface elasticity and residual surface stress are taken into consideration. Using Hamilton’s principle, t...
Large amplitude forced vibration behaviour of stiffened plates under harmonic excitation is studied numerically incorporating the effect of geometric non-linearity. The forced vibration analysis is carried out in an indirect way in which the dynamic system is assumed to satisfy the force equilibrium condition at peak excitation amplitude. Large amplitude free vibration analysis of the same syst...
