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 ...
Natural frequencies of thin, rectangular plates with holes or orthotropic "patches" carrying an elastically mounted mass
(Pergamon-Elsevier Science Ltd, 2006-07)
The approximate solution for the title problem is obtained in the case of simply supported and clamped rectangular plates made of isotropic or orthotropic materials. A variational approach (the well known Rayleigh-Ritz ...
El método de cuadratura diferencial generalizado: estudio de arcos circulares delgados vibrantesThe generalized differential quadrature method: study of vibrating thin circular arches
(Universitat Politècnica de Catalunya, 2008-12)
Los arcos circulares delgados constituyen un tema de permanente interés en el campo de la ingeniería estructural. En muchas de sus aplicaciones, el ingeniero de diseño necesita disponer de parámetros dinámicos que caractericen ...
