A BEM model applied to failure analysis of multi-fractured structures

Due to manufacturing or damage process, brittle materials present a large number of micro-cracks which are randomly distributed. The lifetime of these materials is governed by crack propagation under the applied mechanical and thermal loadings. In order to deal with these kinds of materials, the present work develops a boundary element method (BEM) model allowing for the analysis of multiple random crack propagation in plane structures. The adopted formulation is based on the dual BEM, for which singular and hyper-singular integral equations are used. An iterative scheme to predict the crack growth path and crack length increment is proposed. This scheme enables us to simulate the localization and coalescence phenomena, which are the main contribution of this paper. Considering the fracture mechanics approach, the displacement correlation technique is applied to evaluate the stress intensity factors. The propagation angle and the equivalent stress intensity factor are calculated using the theory of maximum circumferential stress. Examples of multi-fractured domains, loaded up to rupture, are considered to illustrate the applicability of the proposed method. (C) 2011 Elsevier Ltd. All rights reserved.

BEM formulation for von Karman plates

This work deals with nonlinear geometric plates in the context of von Karman`s theory. The formulation is written such that only the boundary in-plane displacement and deflection integral equations for boundary collocations are required. At internal points, only out-of-plane rotation, curvature and in-plane internal force representations are used. Thus, only integral representations of these values are derived. The nonlinear system of equations is derived by approximating all densities in the domain integrals as single values, which therefore reduces the computational effort needed to evaluate the domain value influences. Hyper-singular equations are avoided by approximating the domain values using only internal nodes. The solution is obtained using a Newton scheme for which a consistent tangent operator was derived.

An extended BEM formulation for plates reinforced by rectangular beams

This article presents a BEM formulation developed particularly for analysis of plates reinforced by rectangular beams. This is an extended version of a Previous paper that only took into account bending effects. The problem is now re-formulated to consider bending and membrane force effects. The effects of the reinforcements are taken into account by using a simplified scheme that requires application of ail initial stress field to locally correct the bending and stretching stiffness of the reinforcement regions. The domain integrals due to the presence of the reinforcements are then transformed to the reinforcement/plate interface. To reduce the number of degrees of freedom related to the presence of the reinforcement, the proposed model was simplified to consider only bending and stretching rigidities in the direction of the beams. The complete model can be recovered by applying all six internal force correctors, corresponding to six degrees of freedom per node. Examples are presented to confirm the accuracy of the formulation and to illustrate the level of simplification introduced by this strong reduction in the number of degrees of freedom.

BEM formulation for reinforced plates

This article presents a BEM formulation developed to analyse reinforced plate bending. The reinforcements are formulated using a simplified scheme based on applying an initial moment field adopted to locally correct the stiffness of the reinforcement regions. The domain integrals due to the presence of the reinforcements are then transformed to the reinforcement/plate interface. The increase in system stiffness due to the reinforcements can be taken into account independently for each coefficient. Thus, one can conveniently reduce the number of degrees of freedom required in considering the reinforcement. Only one degree-of-freedom is required at each internal node when taking into account only the flexural stiffness of beams. Examples are presented to confirm the accuracy of the formulation.

An alternative multi-region BEM technique for three-dimensional elastic problems

The main objective of this work is to present an alternative boundary element method (BEM) formulation for the static analysis of three-dimensional non-homogeneous isotropic solids. These problems can be solved using the classical boundary element formulation, analyzing each subregion separately and then joining them together by introducing equilibrium and displacements compatibility. Establishing relations between the displacement fundamental solutions of the different domains, the alternative technique proposed in this paper allows analyzing all the domains as one unique solid, not requiring equilibrium or compatibility equations. This formulation also leads to a smaller system of equations when compared to the usual subregion technique, and the results obtained are even more accurate. (C) 2008 Elsevier Ltd.

QUADRANT-SEARCHING: A NEW TECHNIQUE TO REDUCE THE SEARCH SPACE OF THE INVERSE PROBLEM OF EIT USING BEM TO THE DIRECT PROBLEM

The image reconstruction using the EIT (Electrical Impedance Tomography) technique is a nonlinear and ill-posed inverse problem which demands a powerful direct or iterative method. A typical approach for solving the problem is to minimize an error functional using an iterative method. In this case, an initial solution close enough to the global minimum is mandatory to ensure the convergence to the correct minimum in an appropriate time interval. The aim of this paper is to present a new, simple and low cost technique (quadrant-searching) to reduce the search space and consequently to obtain an initial solution of the inverse problem of EIT. This technique calculates the error functional for four different contrast distributions placing a large prospective inclusion in the four quadrants of the domain. Comparing the four values of the error functional it is possible to get conclusions about the internal electric contrast. For this purpose, initially we performed tests to assess the accuracy of the BEM (Boundary Element Method) when applied to the direct problem of the EIT and to verify the behavior of error functional surface in the search space. Finally, numerical tests have been performed to verify the new technique.

?? poss??vel comprar bem no servi??o p??blico

A id??ia desse projeto surgiu a partir de uma experi??ncia junto ?? Comiss??o Permanente de Licita????o ??? CPL da ENAP, onde se constatava freq??entemente a baixa qualidade dos produtos adquiridos com pre??os elevados, um processo de compras muito demorado e um reduzido n??mero de fornecedores. A CPL prop??s mudan??as, recriou os processos e redefiniu as responsabilidades entre as unidades gestoras da institui????o. Com cerca de um ano e meio de experi??ncia implementada as mudan??as j?? foram observadas, quais sejam: queda significativa dos pre??os dos produtos e servi??os oferecidos pelo mercado, aumento do n??mero de fornecedores, melhoria na qualidade dos produtos e servi??os adquiridos, transpar??ncia e maior brevidade no processo de compras

Avaliação do processamento auditivo em idosos que relatam ouvir bem

Em idosos, os resultados da avaliação comportamental das vias auditivas centrais são considerados de difícil interpretação devido à possível interferência do comprometimento das vias auditivas periféricas. OBJETIVO: Avaliar a eficiência das funções auditivas centrais de idosos que relatam ouvir bem. MATERIAL E MÉTODO: Estudo de casos que incluiu 40 indivíduos na faixa etária de 60 a 75 anos. Os pacientes foram submetidos à avaliação do processamento auditivo que constou de anamnese, exame otorrinolaringológico, audiometria tonal liminar, limiar de reconhecimento de fala, índice de reconhecimento de fala, imitanciometria, pesquisa de reflexos estapedianos, teste de identificação de sentenças sintéticas com mensagem competitiva ipsilateral, teste de padrões de freqüência e teste de dissílabos alternados por meio de tarefa dicótica. RESULTADOS: Gênero, faixa etária e perda auditiva não influenciaram os resultados dos testes de padrões de freqüência e dissílabos alternados por meio de tarefa dicótica; faixa etária e perda auditiva influenciaram os resultados do teste de identificação de sentenças com mensagem competitiva ipsilateral. Porcentagens de acertos abaixo dos padrões da normalidade de adultos foram observadas nos três testes que acessam as funções auditivas centrais. CONCLUSÃO: Indivíduos idosos que relatam ouvir bem apresentam prevalência relevante de sinais de ineficiência das funções auditivas centrais.
