In this paper, a new analytical method for vibration analysis of a cracked simply supported beam is investigated. By considering a nonlinear model for the fatigue crack, the governing equation of motion of the cracked beam is solved using perturbation method. The solution of the governing equation r
An analytical model is proposed which consists of two Euler-Bernoulli beams joined by a torsional spring with linear and cubic stiffness. The method of harmonic balance is used to find an approximate solution for simply supported and clamped end conditions. Specifically, a one term harmonic balance
An analytical transfer matrix method is used to solve the direct and inverse problems of simply supported beams with an open crack. The crack is modeled as a rotational spring with sectional flexibility. By using the Timoshenko beam theory on two separate beams respectively and applying the compatib
The modal frequencies and loss factors of a simply supported beam with an enhanced active constrained layer (EACL) damping treatment are derived by the extended Hamilton principle and Rayleigh-Ritz method while open-and closed-loop control (displacement and velocity feedback) systems are considered.
