[pt] AVALIAÇÃO DO COMPORTAMENTO MECÂNICO DE PAINÉIS SANDUÍCHE COM COMPÓSITOS LAMINADOS REFORÇADOS COM FIBRA DE CURAUÁ E NÚCLEO DE CONCRETO CELULAR AUTOCLAVADO / [en] EVALUATION OF THE MECHANICAL BEHAVIOR OF SANDWICH PANELS WITH CURAUÁ FIBER-CEMENT COMPOSITE LAYERS AND AUTOCLAVED AERATED CONCRETE COREISABELA DE PAULA SALGADO 19 December 2019 (has links)
[pt] O presente trabalho propõe-se a analisar o comportamento mecânico de painéis sanduíche constituídos por duas camadas externas de compósitos cimentícios reforçados com fibras naturais, separadas por um núcleo de concreto celular autoclavado (CCA). Cada placa de material compósito foi moldada diretamente sobre a superfície de um bloco de CCA, por meio da disposição manual de três camadas unidirecionais de fibras longas de curauá. Visando prover maior durabilidade ao compósito, desenvolveu-se uma matriz com baixo teor de hidróxido de cálcio, substituindo uma parcela do cimento por materiais pozolânicos. Ensaios de caracterização da matriz, dos filamentos de curauá e dos blocos de CCA foram realizados para a obtenção de suas propriedades independentes. Os compósitos foram submetidos a ensaios de arrancamento do tecido, tração direta e flexão a quatro pontos para a avaliação de diferentes aspectos de seus mecanismos de fissuração, resistência e capacidade de deformação. Zonas de carregamento foram indicadas em cada caso para demonstrar o comportamento padrão dos compósitos. Os painéis sanduíche, por sua vez, foram analisados em termos de interface, por meio de ensaios de aderência e micrografias da superfície de transição dos materiais, e de desempenho mecânico, por ensaios de flexão a quatro pontos cíclicos e monotônicos. Esses últimos forneceram a rigidez, capacidade de carga e deflexão dos painéis sanduíche, tal como as principais propriedades de seus elementos: para o núcleo, a resistência ao cisalhamento e o módulo de cisalhamento, e para as lâminas, a resistência à compressão e à tração. Os ensaios cíclicos testaram a resistência do material a séries de carregamento-descarregamento, enquanto ensaios de aderência foram utilizados para verificar a
interface entre os compósitos laminados e o núcleo de CCA. Os resultados indicaram um desempenho satisfatório dos painéis sanduíche, uma vez que os compósitos foram capazes de lhes fornecer um comportamento de strain/deflection hardening, aumentando sua resistência e tenacidade. A adesão entre lâminas-núcleo mostrou-se eficaz, de maneira que os diferentes materiais compreendidos demonstraram interação adequada entre si, bem como propriedades complementares. Dentre os objetivos desse trabalho, encontra-se o desenvolvimento de um material sustentável, leve, resistente e tenaz, de modo que constitua uma alternativa promissora e de baixo custo a aplicações de Engenharia. / [en] This present work aims to analyze the mechanical behavior of sandwich panels consisting of two outer layers of natural fiber-reinforced cementitious composites separated by a core layer of autoclaved aerated concrete (AAC). The molding of each composite layer was made directly on the surface of an AAC block, by manually arranging three layers of long unidirectional aligned curauá fibers in the mortar. In order to increase the composite durability, a matrix with a low content of calcium hydroxide was developed, where the Portland cement was partially replaced by pozzolanic materials. Characterization tests of the matrix, the curauá filaments and the AAC blocks were performed to obtain their independent properties. The composites were submitted to fabric pull-out tests, direct tensile tests and four-point bending to evaluate different aspects of their cracking mechanisms, strength and deformation capacity. Loading zones were indicated in each case to demonstrate the standard composite behavior. The sandwich panels, on the other hand, were analyzed in terms of interface, through pull-off tests and SEM images of the materials transition surface, and mechanical performance, by means of cyclic and monotonic four-point bending tests. The latter registered the rigidity, load capacity and deflection of the sandwich panels, as well as the main properties of their elements: for the core, shear strength and shear modulus, and for the skin layers, compressive strength and tensile strength. Cyclic tests evaluated the resistance of the material to loading-unloading cycles, while pull-off tests were used to verify the interface between the laminated composites and the AAC core. The results indicated a satisfactory performance of the sandwich panels, since the composite layers provided a strain/deflection hardening behavior to the material,
increasing its flexural strength and toughness. The adhesion between the layers and the core proved to be effective, so that the comprised materials displayed adequate interaction between each other, as well as complementary properties. Among the objectives of this work is the development of a sustainable, lightweight, resistant and tough material, in a way that it represents a promising and low-cost alternative to Engineering applications.

Global and Local Buckling Analysis of Stiffened and Sandwich Panels Using Mechanics of Structure GenomeNing Liu (6411908) 10 June 2019 (has links)
Mechanics of structure genome (MSG) is a unified homogenization theory that
provides constitutive modeling of three-dimensional (3D) continua, beams and plates.
In present work, the author extends the MSG to study the buckling of structures such
as stiffened and sandwich panels. Such structures are usually slender or flat and easily
buckle under compressive loads or bending moments which may result in catastrophic
failure.<div><br><div>Buckling studies of stiffened and sandwich panels are found to be scattered. Most
of the existed theories employ unnecessary assumptions or only apply to certain types
of structures. There are few unified approaches that are capable of studying the
buckling of different kinds of structures altogether. The main improvements of current
approach compared with other methods in the literature are avoiding unnecessary
assumptions, the capability of predicting all possible buckling modes including the
global and local buckling modes, and the potential in studying the buckling of various
types of structures.<br></div><div><br></div><div>For global buckling that features small local rotations, MSG mathematically decouples
the 3D geometrical nonlinear problem into a linear constitutive modeling using
structure genome (SG) and a geometrical nonlinear problem defined in a macroscopic
structure. As a result, the original structures are simplified as macroscopic structures
such as beams, plates or continua with effective properties, and the global buckling
modes are predicted on macroscopic structures. For local buckling that features
finite local rotations, Green strain is introduced into the MSG theory to achieve geometrically nonlinear constitutive modeling. Newton’s method is used to solve
the nonlinear equilibrium equations for fluctuating functions. To find the bifurcated
fluctuating functions, the fluctuating functions are then perturbed under the Bloch-periodic
boundary conditions. The bifurcation is found when the tangent stiffness
associated with the perturbed fluctuating functions becomes singular. Moreover, the
arc-length method is introduced to solve the nonlinear equilibrium equations for post-local-buckling
predictions because of its robustness. The imperfection is included in
the form of geometrical imperfection by superimposing the scaled buckling modes in
linear perturbation analysis on mesh.<br></div><div><br></div><div>Extensive validation case studies are carried out to assess the accuracy of the
MSG theory in global buckling analysis and post-global-buckling analysis, and assess
the accuracy of the extended MSG theory in local buckling and post-local-buckling
analysis. Results using MSG theory and extended MSG theory in buckling analysis
are compared with direct numerical solutions such as 3D FEA results and results in
literature. Parametric studies are performed to reveal the relative influence of selective
geometric parameters on buckling behaviors. The extended MSG theory is also
compared with representative volume element (RVE) analysis with Bloch-periodic
boundary conditions using commercial finite element packages such as Abaqus to
assess the efficiency and accuracy of the present approach.<br></div></div>
