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 ...
Análise de vigas de Timoshenko pelo Método dos Elementos Finitos
(Universidade Federal do Rio Grande do NorteBrasilUFRNEngenharia Civil, 2019-05-23)
This work aims to analyze the structural behavior of beams in linear elastic regime by the Finite Element Method (MEF) based on the Timoshenko Beam Theory. A numerical study of the problem was developed and used as a base ...
Timoshenko versus Euler beam theory: Pitfalls of a deterministic approach
(ELSEVIER SCIENCE BV, 2011)
The selection criteria for Euler-Bernoulli or Timoshenko beam theories are generally given by means of some deterministic rule involving beam dimensions. The Euler-Bernoulli beam theory is used to model the behavior of ...
Vibration analysis of rotating Timoshenko beams by means of the differential quadrature method
(Techno-Press, 2010-02)
Vibration analysis of rotating beams is a topic of constant interest in mechanical engineering. The differential quadrature method (DQM) is used to obtain the natural frequencies of free transverse vibration of rotating ...
