Análise dinâmica não-linear de lajes em concreto armado sob ação de cargas impulsivas provenientes de explosão: .
(Universidade Federal de Minas GeraisUFMG, 1991-07-11)
Criteria and prcedures for the dynamic non-linear analysis of retangular reinforced plates subjected to impulsive loads from explosions are presented in this work. Simple supports and clamped adges are the boundary conditions ...
Reduced order modeling of composite laminates through solid-shell coupling
(2017)
© 2017, Journal of Aerospace Technology and Management. All rights reserved.Composite laminates display a complex mechanical behavior due to their microstructure, with a through-thickness variation of the displacement and ...
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 Discontinuous Petrov–Galerkin Method for Reissner–Mindlin Plates
(2023)
We present a discontinuous Petrov–Galerkin method with optimal test functions for the Reissner–Mindlin plate bending model. Our method is based on a variational formulation that utilizes a Helmholtz decomposition of the ...
Free vibrations of anisotropic rectangular plates with holes and attached masses
(Techno-Press, 2008-01-10)
Anisotropic materials are increasingly required in modern technological applications. Certainly, civil, mechanical and naval engineers frequently deal with the situation of analyzing the dynamical behaviour of structural ...

Natural frequencies of thin rectangular plates with partial intermediate supports
(Plapiqui, 2004-12)
In the present study, a methodology to find natural frequencies with arbitrary precision of thin rectangular plates on linear intermediate supports and mixed boundary conditions is presented. This means that the edges are ...
Evolution of instabilities in filament buckling processes
(American Physical Society, 2019-03)
In this work we study the dynamical buckling process of a thin filament immersed in a highly viscous medium. We perform an experimental study to track the shape evolution of the filament during a constant velocity compression. ...
Experimental and computational analysis of plates under air blast loading
(Pergamon-Elsevier Science Ltd, 2001-11)
The main objective of this paper is the comparison between testing and numerical responses of metallic plates subjected to explosive loads, in order to obtain guides to the numerical modeling and analysis of this phenomenon. ...
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 ...
