Variational method for non-conservative instability of a cantilever SWCNT in the presence of variable mass or crack
(Springer, 2021-01)
In the present paper, the non-conservative instability of a cantilever single-walled carbon nanotube (SWCNT) through nonlocal theory is investigated. The nanotube is modeled as clamped-free beam carrying a concentrated ...
Análise de modelos matemáticos de pilar-parede pelo MEF
(Universidade Federal do Rio Grande do NorteBrasilUFRNEngenharia Civil, 2019)
In this work, mathematical models with increasing degree of complexity were used to idealize shear wall structures with U, C and E cross section, using the commercial code ADINA, based on the Finite Element Method. Four ...
Formulação para a análise avançada de sistemas estruturais formados por cabos e treliças espaciais visando à aplicação em torres estaiadas para linhas de transmissão
(Universidade Federal de Minas GeraisUFMG, 2014-12-14)
This research aims to develop a general formulation using the Finite Element Method (FEM) to perform an advanced analysis of structural systems composed by cables and space trusses structures and its computational ...
Comparación teórica entre el método puntal tensor y el método de elementos finitos aplicado a dados de transferencia en puentes vehiculares
(Escuela Colombiana de Ingeniería Julio GaravitoIngeniería CivilACI - Seccional ColombiaMaestría en Ingeniería Civil, 2021)
The structural design of pile caps involves determining an accurate internal stress flow system which leads to suitable member dimensioning and steel reinforcement. However, It has been found out that finite element analyses ...
Relações entre propriedades de rigidez de madeiras do grupo das folhosas
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Engenharia Civil - PPGECivCâmpus São Carlos, 2019-12-13)
For a correct timber structures design, it is necessary to know the physical and mechanical properties of the material. Among these properties, the modulus of elasticity is highly important, in view of its use in the ...
Vibration Analysis Of Flexible Rotating Rings Using A Spectral Element Formulation

Vibrations of L-Shaped Beam Structures With a Crack: Analytical Approach and Experimental Validation
(Wiley Blackwell Publishing, Inc, 2016-06-25)
A crack on a structural member introduces a local flexibility which is function of the crack depth. This new flexibility condition changes the dynamic behavior of the structure. The knowledge of the influence of the crack ...
Nonlocal frequency analysis of nanosensors with different boundary conditions and attached distributed biomolecules: an approximate method
(Springer Wien, 2016-04-26)
Nanosensors are simple engineering devices designed to detect and convey informations about nanoparticles and biomolecules. The nanosized mass sensors are based on the fact that the resonant frequency is sensitive to the ...
