Clamped plates considered as three-dimensional solids: A method to find arbitrary precision frequencies
(Academic Press Ltd - Elsevier Science Ltd, 2001-12)
In this paper, the plate is assumed as a regular prism of arbitrary aspect ratio and thickness with four consecutive faces clamped. By increasing the thickness from zero, one may model the thin, moderately thick and thick ...
Free Vibrations of Beam System Structures with Elastic Boundary Conditions and an Internal Elastic Hinge
(Hindawi Publishing Corporation, 2013-09)
The study of the dynamic properties of beam structures is extremely important for proper structural design. This present paper deals with the free in-plane vibrations of a system of two orthogonal beam members with an ...
Dynamic stationary response of reinforced plates by the boundary element method
(Hindawi Publishing Corporation, 2007-01-01)
A direct version of the boundary element method (BEM) is developed to model the stationary dynamic response of reinforced plate structures, such as reinforced panels in buildings, automobiles, and airplanes. The dynamic ...

Minimization of the first eigenvalue in problems involving the bi-laplacianMinimization of the first eigenvalue in problems involving the bi-laplacian
(2009-02-27)
This paper concerns the minimization of the first eigenvalue in problems involvingthe bi-Laplacian under either homogeneous Navier boundary conditions or homogeneousDirichlet boundary conditions. Physically, in case of N ...
Tides and wind-driven circulation in the tropical and Southern Atlantic Ocean: the BRAZCOAST system
(Institute of Atmospheric PhysicsBeijing, 2014)
The Brazilian coast is characterized by different
tidal regimes and distinct meteorological influences.
The northern part has larger tidal amplitudes and is
permanently affected by trade winds and tropical disturbances;
the ...
Exact expressions for numerical evaluation of high order modes of vibration in uniform Euler-Bernoulli beams
(2018-12-01)
In the literature, expressions can be found for the mode shape functions of uniform Euler-Bernoulli beams. However, these expressions permit the evaluation of only the first 12 modes or so due to numerical issues associated ...
A transmission problem for beams on nonlinear supports
(2006)
A transmission problem involving two Euler-Bernoulli equations modeling the vibrations of a composite beam is studied. Assuming that the beam is clamped at one extremity, and resting on an elastic bearing at the other ...
Transverse vibrations of circular annular plates with edges elastically restrained against rotation, used in acoustic underwater transducers
(Pergamon-Elsevier Science Ltd, 2002-04)
Simply supported or clamped boundary conditions are rather ideal situations difficult to satisfy from a physical viewpoint. This paper considers a more "moderate" restriction: the case of edges elastically restrained against ...
Formulación y ensamblaje de elementos finitos jerárquicos para el análisis estático y dinámico de placas cuadriláteras laminadasFormulation and assembly of hierarchical finite elements to the static and dynamic analysis of laminated quadrilateral plates
(Associação Sul Americana de Engenharia Estrutural, 2012-01)
En este trabajo se presenta la formulación y el proceso de ensamblaje de elementos finitos enriquecidos con polinomios ortogonales de Gram-Schmidt para el estudio de placas. A través del proceso de ensamblaje es posible ...
