Describing hysteretic systems with a closed-form solution is a challenging task due to some pitfalls regarding the non-smooth and memory effect mechanisms that do not permit, for example, to apply conventional frequency ...

As estruturas que exibem comportamento de histerese podem apresentar efeitos dinâmicos complexos que restringem a aplicação de técnicas convencionais de identificação. Entre os vários sistemas nos quais estes efeitos estão ...

This paper is concerned with the Sommerfeld effect (Jump phenomena) attenuation in an non-ideal mechanical oscillator connected with an unbalanced motor excitation with a limited power supply (non-ideal system) using a ...

Structures joined by lap-joints can present complex nonlinear dynamic behavior as a function of the stress to which the lap-joint is subjected, including contact stiffness variations and softening, along with hysteresis ...

The present study deals with three different methods for structural identification: the Kalman filter, the Unscented Kalman filter and the Particle filter. The Kalman filter is a known filter for state estimation in linear ...
