Natural vibrations of micro beams with nonrigid supports
(Sage Publications Ltd, 2016-01)
The present study aims to provide some new information for the design of micro systems. It deals with free vibrations of Bernoulli–Euler micro beams with nonrigid supports. The study is based on the formulation of the ...
Effective Electromechanical Coupling Coefficients of Piezoelectric Adaptive Structures: Critical Evaluation and Optimization
(TAYLOR & FRANCIS INC, 2009)
This work presents a critical analysis of methodologies to evaluate the effective (or generalized) electromechanical coupling coefficient (EMCC) for structures with piezoelectric elements. First, a review of several existing ...
A coupled boundary element/differential equation method formulation for plate-beam interaction analysis
(ELSEVIER SCI LTD, 2010)
In this work, a new boundary element formulation for the analysis of plate-beam interaction is presented. This formulation uses a three nodal value boundary elements and each beam element is replaced by its actions on the ...
Refined sandwich model for the vibration of beams with embedded shear piezoelectric actuators and sensors
(PERGAMON-ELSEVIER SCIENCE LTD, 2008)
This work extends a previously presented refined sandwich beam finite element (FE) model to vibration analysis, including dynamic piezoelectric actuation and sensing. The mechanical model is a refinement of the classical ...
A 1D model for the dynamic analysis of magneto-electro-elastic beams with curved configuration
(Pergamon-Elsevier Science Ltd, 2015-07)
The scope of the present paper is to present some new contributions in the dynamics of curved/straight MEE beams. The structure consists of a curved beam constructed with ceramic/metallic materials whose elastic behavior ...
Influence of nonlinear stiffness on the dynamics of a slender elastic beam under torsional oscillations
(2014)
This study focuses on analysing the effects of nonlinear torsional stiffness on the dynam-ics of a slender elastic beam under torsional oscillations, which can be subject to helical buckling.The helical buckling of an ...
Use of the dynamic stiffness method to interpret experimental data from a nonlinear system
(2018-01-01)
The interpretation of experimental data from nonlinear structures is challenging, primarily because of dependency on types and levels of excitation, and coupling issues with test equipment. In this paper, the use of the ...
Dynamics of magneto electro elastic curved beams: Quantification of parametric uncertainties
(Elsevier, 2015-12-01)
The objective of this paper is the evaluation of uncertainty propagation associated to several parameters in the dynamics of magneto-electro-elastic (MEE) curved beams. These MEE structures can be employed as imbedded parts ...
Shear-deformable thin-walled composite beams in internal and external resonance
(Elsevier, 2013-03)
The non-linear dynamic response of thin-walled composite beams is analyzed considering the effect of shear deformation. The model is based on a small strain and large rotation and displacements theory, which is formulated ...
Critical coupling layer thickness for positive or negative Goos-Hänchen shifts near the excitation of backward surface polaritons in Otto-ATR systems
(IOP Publishing, 2015-05)
We present a theoretical analysis of the lateral displacement (Goos-Hänchen shift) of spatially limited beams reflected from attenuated total reflection (ATR) devices in the Otto configuration when backward surface plasmon ...
