Theoretical and experimental researches of post-micro-buckling for fiber-reinforced composites

Post-microbuckling is a fundamental feature of compressive failure process for the unidirectional-fiber-reinforced composites and laminated composites. The post-microbuckling behavior of composites under compression in the light of the Kevlar49-reinforced 648/BF3.400 (brittle epoxy) and EP (flexible epoxy) is studied, theoretically and experimentally. Analytical results of compressive strength are in good agreement with experimental results, qualitatively and quantitatively. By the experimental research, the post-microbuckling feature of the advancing kink band model is clearly displayed.

Evolution of ideal micro-crack system

The ideal micro-cracks are treated with the number-density function; the characteristics of their evolution are investigated; a deterministic model is applied to the discussion of their extension. It is discovered that under certain conditions saturation may occur in the number-density. The main features of the statistical formulation are illustrated by several examples and compared with those observed in experiments.

Frente Parlamentar Mista das Micro e Pequenas Empresas : lógica de funcionamento e resultados

Analisa o modo com que os parlamentares se organizam frente à estrutura institucional no Congresso Nacional. Tem como referências para discussão, contribuições de Barry Ames (2003) e Figueiredo e Limongi (2001) que apresentam dois modelos de funcionamento do Parlamento, o distributivista e o partidário. Analisa a atuação da Frente Parlamentar Mista das Micro e Pequenas Empresas. Enfatiza a segunda fase de funcionamento da Frente, os anos de 2008 e 2009, quando trabalhou pela regulamentação da Lei Geral das Micro e Pequenas Empresas (Lei Complementar nº 123/06) nos Estados e Municípios e seus aperfeiçoamentos por meio da aprovação de Leis Complementares nºs 127/07, 128/08 e 133/09.

Valoración de la Cooperación Inter-empresarial en las Microempresas del Municipio de Murcia, proyectos Micro y e-Micro (2002-2007)

[ES] El marco teórico del trabajo tiene como finalidad explicar los procesos de cooperación diseñados para las microempresas, con el propósito de establecer propuestas y argumentos para la formación de acuerdos, identificar los factores que afectan el desarrollo de los mismos, así como los sistemas de innovación nacional, regional y local para la animación de la cooperación entre firmas. Con ello, se propone una metodología para promover la cooperación entre microempresas, coordinada por agentes locales y la administración pública de los proyectos Micro y e-Micro (2002-2007) de la ciudad de Murcia.

Formation and Structure of Composite Coating of HAD and Micro-Plasma Oxidation on A3 Steel

Composite coatings were obtained on A3 steel by hot dipping aluminum(HAD) at 720 degreesC for 6 min and micro-plasma oxidation (MPO) in alkali electrolyte. The surface morphology, element distribution and interface structure of composite coatings were studied by means of XRD, SEM and EDS. The results show that the composite coatings obtained through HAD/MPO on A3 steel consist of four layers. From the surface to the substrate, the layer is loose Al2O3 ceramic, compact Al2O3 ceramic, At and FeAl intermetallic compound layer in turn. The adhesions among all the layers are strengthened because the ceramic layer formed at the At surface originally, FeAl intermetallic compound layer and substrate are combined in metallurgical form through mutual diffusion during HAD process. Initial experiment results disclose that the anti-corrosion performance and wear resistance of composite coating are obviously improved through HAD/MPO treatment.

Edge and Size Effects in Micro Composite Structure

Because of the load transfer effect of interface layer, the stress distribution inside the composite structure of film/substrate can be very different from the Timoshenko's model. In this paper, we give the derivation and analysis of such load transfer effect of shear-lag (S-L) model. The micro-structure size (boundary conditions) effect together with interface load transfer effect becomes more and more important as the microstructure size including the three dimensions of thickness, width and length shrinks. The microstructure size is also responsible for the so-called edge-induced stress. The edge effect and difference of S-L model and Timoshenko model are also demonstrated.

The Droplet Group Micro-Explosions, Viscosity and Atomization Characteristics of W/O Emulsions

The spray of emulsified fuel, composed of diesel fuel, water and methanol can make micro-explosion under high temperature conditions, and the viscosity and the atomization characteristics of emulsion have significant effects on the micro- explosion of emulsions. To clarify the combustion mechanism of water-in-oil emulsion sprays, combustion bomb experiments were carried out, and the droplet group micro- explosions in W/O fuel emulsion sprays in a high-pressure, high-temperature bomb were observed clearly by a multi-pulsed, off-axis, image-plane ruby laser holocamera and continuously by a high-speed CCD camera.The viscosity and atomization characteristics of emulsions were also studied experimentally. The experimental results show that the higher concentration of the aqueous phase (water-methanol) (<50%) increases the viscosity of the emulsions, especially for higher agent concentration, and higher aqueous phase concentration and higher viscosity results in lager Sauter Mean Diameter (SMD). The experiment results also show that the different kinds of emulsifying agents, with different Hydrophile-Lipophile Balance (HLB) values, have significant influence on the viscosity of the emulsions.
