Free vibrations of AFG cantilever tapered beams carrying attached masses
(Techno-Press, 2017-03)
The free transverse vibrations of axially functionally graded (AFG) cantilever beams with concentrated masses attached at different points are studied in this paper. The material properties of the AFG beam, consisting of ...
Coupled Free Vibrations Of Tapered Box-Beams Made Of Composite Materials
(Asociación Argentina de Mecánica Computacional, 2006-11)
In this paper, analytical solutions are developed for the free vibration analysis of tapered thin-walled laminated-composite beams with closed cross-sections. The present approach is based in a recently developed model ...
Timoshenko theory effect on the vibration of axially functionally graded cantilever beams carrying concentrated masses
(Techno-Press, 2018-06-25)
In this paper is studied the effect of considering the theory of Timoshenko in the vibration of AFG beams that support ground masses. As it is known, Timoshenko theory takes into account the shear deformation and the ...
Exact solutions for coupled free vibrations of tapered shear-flexible thin-walled composite beams
(Academic Press Ltd - Elsevier Science Ltd, 2008-09-23)
In this paper, analytical solutions for the free vibration analysis of tapered thin-walled laminated-composite beams with both closed and open cross-sections are developed. The present study is based on a recently developed ...
Root Canal Area Increase Promoted by the EndoSequence and ProTaper Systems: Comparison by Computed Tomography
(Elsevier B.V., 2010-07-01)
Introduction: The aim of this study was to compare the increase of the root canal area after instrumentation with EndoSequence or ProTaper rotary systems. Methods: Twenty-two mesial root canals from mandibular molars were ...

Transverse free vibration of non uniform rotating Timoshenko beams with elastically clamped boundary conditions
(Springer, 2013-08)
In the present paper the Differential Quadrature Method, DQM, and the domain decomposition are used to carry out the free transverse vibration analysis of non-uniform multi-span rotating Timoshenko beams with perfect and ...
