Damage detection in nonlinear structures using discrete-time volterra series
(2013-09-16)
Structural damage identification is basically a nonlinear phenomenon; however, nonlinear procedures are not used currently in practical applications due to the complexity and difficulty for implementation of such techniques. ...

Nonlinear Dynamic Behavior, Deterministic Chaos and Nonlinear Control of a Micro Electro Mechanical Actuator System (MEMS)
(Destech Publications, Inc, 2015-01-01)
Micro Electro Mechanical Systems (MEMS) are systems composite by electrical and mechanical devices that interact by means of transducers elements, thus constituting one single and whole system. On the study of dynamic ...
Some remarks on bifurcation analysis of a nonlinear vibrating system excited by a shape memory alloy material (SMA)
(2011-10-01)
In this paper, the dynamical response of a coupled oscillator is investigated, taking in consideration the nonlinear behavior of a SMA spring coupling the two oscillators. Due to the nonlinear coupling terms, the system ...

Modeling the nonlinear behavior of glucose by using the nonlinear step-functions
(Institute of Electrical and Electronics Engineers Inc., 2017-08)
From a sample of 20 type 2 diabetes patients with evidence of exhibiting nonlinear behavior of glucose, we have proposed a mathematical model based on the convolution of the so-called step-function and a full nonlinear ...
Non-parametric identification of a non-linear buckled beam using discrete-time Volterra Series
(2014-01-01)
The consideration of nonlinearities in mechanical structures is a question of high importance because several common features as joints, large displacements and backlash may give rise to these kinds of phenomena. However, ...
Characterization and interaction of geometric and contact/impact nonlinearities in dynamical systems
(2022-03-15)
In this work, we study how a contact/impact nonlinearity interacts with a geometric cubic nonlinearity in an oscillator system. Specific focus is shown to the effects on bifurcation behavior and secondary resonances (i.e., ...
Dynamical behavior and optimization of a nonlinear vibration absorber
(2016-10-01)
The paper concerns the introduction of cubic nonlinearity into a vibration absorber to improve its effectiveness. The nonlinear stiffness is offered by a thin clamped circular plate which undergoes large flexural deflection. ...
