Abstract:

The article presents a reflection on the definition of the feature, which enabled the development of feature-based method for modeling of composite structural components. The need for defining feature is a direct result of the ambiguity of statements or narrow definitions and their applications. So far are well developed feature, which are used in process design (CAD) - geometric feature, design feature and in the process of manufacturing (CAM) - Technology feature, and also focused on functionality (CAE - motion simulation) functional feature. The feature representation of a fully functioning feature-based system that does the aggregation of information about the structure of a construction object made from layered composites.. This approach is based on a single, independent feature representation that can be used for design, finite element analysis, technology process planning. The paper describes the main approach to the engineering analysis with the use of FEM and a convenient method of simplifying the geometry of the model and the composition of the composite. Also discussed are possible extensions to features to enhance the finite element meshing process.

Abstract:

This paper presents a theory and applications to account for changes in the fundamental, buckling, and post-buckling states when design parameters of a composite material are modified. The influence of micro-mechanical parameters (the volume fraction and the fiber orientation) and of cross-sectional dimensions is investigated. A numerical example for columns made of composite materials is presented. Sensitivity is studied for local buckling loads. Explicit expressions are obtained for the sensitivities in the form of perturbation expansions. A beam under transverse load is also investigated, and geometric design parameters employed to investigate sensitivity. The information from the sensitivity analysis can be used to improve a design by modification of the buckling load.

Abstract:

FRCM (Fabric Reinforced Cementitious Matrix) composites are the next stage of development of composite structural reinforcement after FRP (Fibre Reinforced Polymers) composites. The main element that distinguishes the newer FRCM system is the matrix of the composite – mineral matrix instead of epoxy resin. Changes in the structure of the composite, resulting from the change of the matrix, have a big impact on its work mechanisms. This paper discusses FRCM composites and shows its effectiveness in reinforced concrete elements strengthening. The basic information on FRCM mesh fibres material differences and composite failure modes are given. Current trends and directions of composite structural strengthening and the latest research in the area of increasing FRCM composite strengthening effectiveness, that are being conducted by the authors, are presented.

Abstract:

The present document covers the studies over Structural Health Monitoring systems via vibration based methods. The topic is organized in two parallel studies. The first one analyzes the integrity of metal-composite single lap bonded joints. The second one approaches similar analyses for sandwich structures. The monitoring was made by investigating the dynamic response both computationally and experimentally to verify the reliability of applying vibration based SHM procedures, specifically with the objective of identifying the presence of debonding damage. The dynamic responses were obtained via accelerometers and piezoelectric sensors placed on top of the investigated structures (on the outward surface). The purpose for the accelerometers is to provide reference data for the analyses involving the piezoelectric sensors. Different metrics of damage identification were investigated, all working over a determined frequency range. They quantify the damage by analyzing either the magnitudes or phase angles of the dynamic responses among the undamaged and damage structures. This present work proposed modifications to some methodologies of damage quantification found in the literature and compared the results. The new metrics offered more reliable values for the damage quantification on several of the analyses. It was verified that the metrics are valid for the scenarios observed in the present study. The experimental analyses showed also the influence on the dynamic response due to the position of small elastomeric elements. In regards to the finite element analyses, the computational models showed similar results to the experimental data, the more accurate ones being the models for the bonded joints. For the computational models, improvements can be applied into the piezoelectric sensor (e.g. by using new finite element formulations), as well as the region of debonding (e.g. by using contact algorithms). It is important to highlight that the elastic properties of the skins for the sandwich structure were obtained by the literature, so the model can be improved in the future by applying properties obtained experimentally.
Esta dissertação aborda os estudos realizados no campo de Sistemas de Monitoramento da Integridade Estrutural por meio de métodos baseados em vibrações. O tópico abordado é organizado em dois estudos paralelos. O primeiro é relativo ao monitoramento da integridade de juntas coladas metal-compósito. O segundo versa sobre análises semelhantes em estruturas sanduíche. O monitoramento foi executado através das análises das assinaturas dinâmicas das estruturas, tanto computacionalmente quanto experimentalmente, visando avaliar a capacidade de metodologias vibracionais de SHM em detectar dano de descolamento. As respostas dinâmicas foram obtidas por meio de acelerômetros e sensores piezelétricos dispostos sobre a superfície das estruturas avaliadas. Os acelerômetros fornecem dados de referência para as análises realizadas com base nas respostas do sensor piezelétrico. Diferentes métricas de identificação de dano são abordadas, sendo que todas estão baseadas em análise no domínio da frequência, utilizando parâmetros de magnitude ou ângulo de fase das estruturas danificadas e intactas. O presente trabalho propôs alterações em algumas das metodologias encontradas na literatura e comparou os resultados das métricas originais com as modificadas. As métricas modificadas apresentaram resultados mais consistentes em vários cenários de análise. Constatou-se também que as métricas abordadas mostram-se válidas para os casos observados no presente estudo. As análises experimentais também evidenciaram a influência na assinatura dinâmica da estrutura sanduíche causada pelo posicionamento de pequenos elementos elastoméricos. Com relação às análises via elementos finitos, os modelos computacionais apresentaram resultados similares aos obtidos experimentalmente, sendo os da junta colada os mais precisos. Tais modelos computacionais podem ser melhorados no futuro por meio de uma modelagem mais detalhada dos elementos piezelétricos (por exemplo: por meio de novas formulações), como também da região de descolamento (por exemplo: por meio da implementação de algoritmos de contato). Deve-se ressaltar também que as propriedades elásticas das lâminas externas da estrutura sanduíche foram obtidas da literatura, assim sendo, o modelo poderá ser melhorado em estudos futuros por meio do emprego de propriedades obtidas experimentalmente.

Abstract:

Este estudo fundamenta-se na análise numérica, via elementos finitos, de pontes em vigas mistas; considera-se a interação de todos os elementos que compõem a estrutura na transferência dos esforços até os apoios. Inicialmente apresenta-se um estado da arte sobre o projeto, execução e análise de pontes em vigas mistas, identificando as simplificações e deficiências existentes no cálculo destas estruturas. O estudo do comportamento estrutural de tabuleiros mistos foi abordado do ponto de vista tridimensional, sendo para isto modelados e analisados tabuleiros com 8, 10, 12, 14, 16, 18, 20, 22, 24 e 26 m. de vão mediante a utilização do programa ANSYS, versão 5.4. Foi estudada a influência que a presença de contraventamentos, espessura da laje, vão e posição da carga móvel na seção transversal exercem na distribuição de cargas nas vigas, sendo para isto considerado comportamento elástico-linear. Realizou-se também uma abordagem ao estudo da redundância estrutural de tabuleiros mistos considerando as não linearidades física e geométricas do conjunto. Foi verificado que tabuleiros sobre duas e quatro vigas mantêm o equilíbrio estático após que uma das vigas sofre fratura, sem experimentar grandes deslocamentos (inferiores ou ligeiramente superiores ao limite L/500).
This work is based in the numerical analysis, by finite elements, of bridge decks with composite beams; in this study the interaction of all the elements that compose the structure is considered in the transference of the efforts to the supports. lnitially, a state of the art on the design, construction and analysis of composite bridge decks is presented, identifying the simplifications adopted, lack of information at the present on the subject and aspects that need further studies on this bridges. The study of the structural behavior of composite bridge decks was approached from a three-dimensional point of view, modeling and analyzing composite decks with 8, 10, 12, 14, 16, 18, 20, 22, 24 and 26 m of span by using the software ANSYS, version 5.4. The influence that the bracing system, thickness of the slab, span and live load position on the deck, over the load distribution in the composite beams, considering linear-elastic behavior, was studied. An approach to the study of the structural redundancy of composite bridge decks was also made, considering the physical and geometric nonlinearities of the structure. lt was verified that decks consisting of two and four composite beams maintain the static equilibrium after the fracture of one of the beams, without large displacements (inferior or lightly superior to the limit L/500).

Abstract:

A otimização estrutural, utilizando ferramentas computacionais é um grande campo de pesquisa na atualidade. Os métodos utilizados, dependendo da complexidade do problema, demandam um grande custo computacional, e por isso vem sendo avaliandas várias técnicas para diminuí-lo. Uma delas é o emprego de técnicas de aproximação de análises, dentre as quais destacam-se as redes neurais, que combinadas aos métodos de otimização e de análises clássicos conseguem bons resultados e reduzem significativamente o tempo de processamento. O emprego dos compósitos laminados como material estrutural vem crescendo nos últimos tempos, incentivado pela suas excelentes propriedades mecânicas e baixo peso. Em consenso com todo o esforço científico dedicado a essa área, o presente trabalho visa a implementação de uma ferramenta computacional capaz de otimizar estruturas complexas fabricadas com tais materiais, a um baixo custo computacional. Com isto em mente, é desenvolvido um sistema de otimização, aproveitando módulos implementados previamente para a análise estática linear e não linear através do método dos elementos finitos (MEF), e o módulo de otimização por algoritmos genéticos. Serão desenvolvidos os módulos de análise modal, para otimizar também estruturas com critérios baseados em freqüências e modos, e o modulo de redes neurais de tipo perceptron para aproximações das análises feitas através do MEF. Alguns exemplos são apresentados para demonstrar que bons resultados são obtidos com a utilização de redes neurais artificiais, cujo treinamento permite poupar tempo computacional proveniente do grande número de análises usualmente necessárias no processo de otimização.
Structural optimization using computational tools has become a major research field in recent years. Methods commonly used in structural analysis and optimization may demand considerable computational cost, depending on the problem complexity. Therefore, many techniques have been evaluated in order to diminish such impact. Among these various techniques, artificial neural networks may be considered as one of the main alternatives, when combined with classic analysis and optimization methods, to reduce the computational effort without affecting the final solution quality. Use of laminated composite structures has been continuously growing in the last decades due to the excellent mechanical properties and low weight characterizing these materials. Taken into account the increasing scientific effort in the different topics of this area, the aim of the present work is the formulation and implementation of a computational code to optimize manufactured complex laminated structures with a relatively low computational cost by combining the Finite Element Method (FEM) for structural analysis, Genetic Algorithms (GA) for structural optimization and Artificial Neural Networks (ANN) to approximate the finite element solutions. The modules for linear and geometrically non-linear static finite element analysis and for optimize laminated composite plates and shells, using GA, were previously implemented. Here, the finite element module is extended to analyze dynamic responses to optimize problems based in frequencies and modal criteria, and a module with perceptron ANN is added to approximate finite element analyses. Several examples are presented to show the effectiveness of ANN to approximate solutions obtained using the FEM and to reduce significatively the computational cost.

Abstract:

In an effort to achieve lighter and more economical space structures, a new patented steel composite member has been suggested and used in the construction of some steel roof structures. This special element has a sandwich construction composed of some strips of steel plates placed longitudinally along a helical wire core. The function of the helical core is to transfer the shear between the flange plates and increase the sectional inertia of the resulting composite member by keeping the flange plates at a desired distance from each other. Because of the lack of research, design engineers usually treat such elements as a solid member as if it has a full shear transfer between the flanges. However, a detailed analysis shows that this is not a valid assumption and leads to very unsafe results. In this context, the purpose of this study is to investigate the behavior of such members under axial compression and determine their effective sectional flexural rigidity by taking into account the shear deformations. This study applies an analytical investigation to a specific form of such elements with four flange plates placed symmetrically around a helical wire core. Five independent parameters of such a member are selected for this purpose. These are the spiral core and core wire diameters, the pitch of the spiral core, and the flange plate dimensions. Elements with varying combinations of the selected parameters are first analyzed in detail by finite element method, and some design charts are generated for the determination of the effective sectional properties to be used in the structural analysis and the buckling loads. For this purpose, an alternative closed-form approximate analytical solution is also suggested.

The objective of this work was to evaluate the influence of the rigidity of the beam-tocolumn connections as well as the transference of forces among the structural components in steel-concrete composite structures. to do this, data regarding the Moment vs. Rotation curve behavior of a concrete filled beam-to-column connection, previously evaluated on a different work was used for comparison. The experimental value of rigidity was inserted into models of plane frames and tridimensional models, in a way that the global stability parameters can be evaluated according to the rotational stiffness of the beam-to-column connections. In order to evaluate the stability, was led in consideration the ABNT NBR 8800:2008 Brazilian code recommendations. For the numeric simulations, the software SAP 2000® was used, in which it was simulated a plane frame model with ten floors, and also a tridimensional frame, varying the number of floors. Once constructed the numerical models, for the plane frame comparative analysis were performed study of the redistribution of forces, of consumption of steel and stability considering that the beam-to-column connections represented in the models, simulate the following situations regarding the system stiffness: rigid and semi-rigid connections and also ratios of experimental stiffness. For the tridimensional model, besides the variation of the stiffness connection the influence of number of floors on the parameters of stability and distribution of forces on structural elements was also analyzed in the present study. The results showed that the stiffness of the beam-to-connections alters the distribution of forces, and that the variation on the number of floors have influence on the global stability parameter. However, it is possible to design structures with semi-rigid beam-to-column connections respecting the normative limits for the parameters of stability and reducing the consumption of steel in the form of profiles.
O objetivo deste trabalho é avaliar a influência da rigidez das ligações viga-pilar no comportamento e na transferência de forças entre componentes estruturais de sistemas estruturados em elementos mistos de aço e concreto. Para isso, serão utilizados dados do comportamento Momento vs. Rotação de uma ligação viga-pilar misto preenchido já investigada experimentalmente. Os resultados experimentais de rigidez serão inseridos em modelos de pórticos planos e tridimensionais, de forma que os parâmetros de estabilidade global possam ser avaliados em função da rigidez da ligação viga-pilar. Para o estudo da estabilidade são consideradas as recomendações da norma brasileira de estruturas de aço e mistas ABNT NBR 8800:2008. Para as simulações numéricas foi utilizado o pacote computacional SAP 2000® no qual foi modelado um pórtico plano com dez pavimentos e um pórtico tridimensional, variando-se o número de pavimentos e a rigidez das ligações. Para o pórtico plano foram realizadas análises comparativas da distribuição de esforços, do consumo de aço e da estabilidade considerando que as ligações viga-pilar representadas no modelo simulem as seguintes situações quanto à rigidez: ligações rígida e semirrígida, cuja rigidez foi determinada experimentalmente, além de parcelas desta rigidez experimental. Para os pórticos tridimensionais, além da variação de rigidez, foi analisada a influência do número de pavimentos sobre os parâmetros de estabilidade e distribuição de esforços nos elementos estruturais. Os resultados mostraram que a rigidez das ligações altera a distribuição dos esforços e a variação no número de pavimentos influencia nos parâmetros de estabilidade global. No entanto, é possível conceber estruturas com ligações viga-pilar semirrígidas respeitando os limites normativos para os parâmetros de estabilidade e reduzindo o consumo de aço sob a forma de perfis.

Abstract:

This study introduces a new three-dimensional (3D) multi-scale constitutive framework for the nonlinear viscoelastic analysis of laminated and pultruded composites. Two previously developed nonlinear micromechanical models for unidirectional and in-plane random composite layers are modified to include time-dependent and nonlinear behavior. A new recursive-iterative numerical integration method is introduced for the Schapery nonlinear viscoelastic model and is used to model the isotropic matrix subcells in the two micromodels. In addition, a sublaminate model is used to provide for a through-thickness 3D nonlinear equivalent continuum of a layered medium. The fiber medium is considered as transversely isotropic and linear elastic. Incremental micromechanical formulations of the above three micromodels are geared towards the time integration scheme in the matrix phase. New iterative numerical algorithms with predictor-corrector type steps are derived and implemented for each micromodel to satisfy both the constitutive and homogenization equations. Experimental creep tests are performed for off-axis pultruded specimens in order to calibrate and examine the predictions of the constitutive framework for the multi-axial nonlinear viscoelastic response. Experimental creep data, available in the literature, is also used to validate the micromodel formulation for laminated composite materials. Nonlinear viscoelastic effects at the matrix level, such as aging, temperature, and moisture effects can be easily incorporated in the constitutive framework. The multi-scale constitutive framework is implemented in a displacement-based finite element (FE) code for the analysis of laminated and pultruded structures. Several examples are presented to demonstrate the coupled multi-scale material and structural analysis.

Abstract:

Steel and composite structures are traditionally designed through strength based calculations. An alternative approach is to consider deformation capacity. Deformation based design enables a more accurate allowance to be made for the spread of plasticity and allows strain hardening to be considered in a systematic manner. Importantly, the level of deformation required by the structure at ultimate limit state to reach the required design capacity can also be assessed. In composite construction, deformation based design enables a more rigorous assessment to be made of the development of strength in the structural system taking due account of the compatibility between the constituent materials. In this paper, recent developments to the deformation based continuous strength method for steel and composite design are described. Comparisons of capacities obtained from experiments and numerical simulations with those predicted using the continuous strength method are presented and discussed. Recommendations for future work on this topic are also set out.

Abstract:

Bio-structures owe their remarkable mechanical properties to their hierarchical geometrical arrangement as well as heterogeneous material properties. This dissertation presents an integrated, interdisciplinary approach that employs computational mechanics combined with flow network analysis to gain fundamental insights into the failure mechanisms of high performance, light-weight, structured composites by examining the stress flow patterns formed in the nascent stages of loading for the rostrum of the paddlefish. The data required for the flow network analysis was generated from the finite element analysis of the rostrum. The flow network was weighted based on the parameter of interest, which is stress in the current study. The changing kinematics of the structural system was provided as input to the algorithm that computes the minimum-cut of the flow network. The proposed approach was verified using two classical problems three- and four-point bending of a simply-supported concrete beam. The current study also addresses the methodology used to prepare data in an appropriate format for a seamless transition from finite element binary database files to the abstract mathematical domain needed for the network flow analysis. A robust, platform-independent procedure was developed that efficiently handles the large datasets produced by the finite element simulations. Results from computational mechanics using Abaqus and complex network analysis are presented.

Abstract:

The continued use of structural plastics in consumer products, industry, and transportation represents a potential source for durable, long lasting, and recyclable roadways. Costs to dispose of reinforced plastics can be similar to procuring new asphalt with mechanical performance exceeding that of the traditional road surface. This project examines improved material development times by leveraging advanced computational material models based on validated experimental data. By testing traditional asphalt and select carbon and glass reinforced composites, both new and recycled, it is possible to develop a finite element simulation that can predict the material characteristics under a number of loads virtually, and with less lead time compared to experimental testing. From the tested specimens, composites show minimal strength degradation when recycled and used within the asphalt design envelopes considered, with an average of 49% less wear, two orders of magnitude higher compressive strength, and three orders for tensile strength. Predictive computational analysis using the validated material models developed for this investigation confirms the long-term durability.
