2. Influence of high-frequency microwave radiation on montmorillonite structure parameters
Resumo A influência da radiação micro-ondas nas alterações estruturais das partículas de montmorilonita foi estudada em uma amostra de argila montmorilonítica. Processos de longo alcance em múltiplas escalas foram induzidos nos aluminossilicatos naturais por radiação de micro-ondas de baixa e média potência (2,45 Hz, 750 W, 10 min). Amostras em p

3. Multi-scale representation of plastic deformation in fiber-reinforced materials: application to reinforced concrete
Abstract Here we present a multi-scale model to carry out the computation of brittle composite materials reinforced with fibers, and we show its application to standard reinforced concrete. The computation is carried out within an operator-split framework on the macro-scale, which allows for different failure mechanisms to develop in separate phases, as both

5. Os processos de urbanização e conversão florestal na Amazônia paraense – um estudo multiescalar
Resumo Na Amazônia brasileira, as dinâmicas de urbanização e conversão florestal possuem lógicas complexas, dependentes de fatores e agentes atuando em diferentes escalas. Este artigo explora a evolução espacial e temporal da urbanização e da conversão florestal na Amazônia, a partir de elementos mensuráveis presentes nestes processos: a expans�

6. POLÍTICAS PÚBLICAS E SUAS PÓS-VIDAS: MERECIMENTO E CIDADANIA HABITACIONAL NO BRASIL DA MOBILIDADE SOCIAL
Políticas econômicas e sociais construíram o caminho para a redução das desigualdades e melhoria de vida de milhões de brasileiros nos anos de 2000. Com base em pesquisa entre recipientes do programa Minha Casa, Minha Vida, discute-se os nexos etnográficos entre políticas públicas e mobilidade ascendente. Seguindo a trajetória pública e privada de

7. Multiscale Failure Analysis of Cylindrical Composite Pressure Vessel: A Parametric Study
Abstract This paper deals with a multiscale approach to model thick-walled laminate cylinder with internal pressure. Micromechanics defines material homogenization considering two steps: determination of equivalent properties of each lamina from matrix and fiber properties according to the Mori-Tanaka model for elastic properties and to the Bridging model fo

8. Perspectives on the modeling of the neuromusculoskeletal system to investigate the influence of neurodegenerative diseases on sensorimotor control
Abstract Introduction The understanding of the neurophysiological mechanisms underlying movement control can be much furthered using computational models of the neuromusculoskeletal system. Biologically based multi-scale neuromusculoskeletal models have a great potential to provide new theories and explanations related to mechanisms behind muscle force gen

9. Comparing the Performance of Ground Filtering Algorithms for Terrain Modeling in a Forest Environment Using Airborne LiDAR Data
ABSTRACT The aim of this study was to evaluate the performance of four ground filtering algorithms to generate digital terrain models (DTMs) from airborne light detection and ranging (LiDAR) data. The study area is a forest environment located in Washington state, USA with distinct classes of land use and land cover (e.g., shrubland, grassland, bare soil, an

10. Experimental Multi-scale analysis of Carbon/Epoxy Composites Nano-Reinforced by Carbon Nanotubes/Multi-layer Graphene
Nano-size structures, nanotubes/multi-layer graphene (CNT/MLG), were dispersed into epoxy system by a combination of sonication and high shear mixing. To avoid CNT/MLG agglomeration, a non-covalent functionalization were performed using surfactants, CO890 - Polyoxyethylene (40) nonylphenyl ether and SDBS - sodium dodecyl benzene sulfonate. Raman spectroscopy

11. Prediction of Plastic Instability in Sheet Metals During Forming Processes Using the Loss of Ellipticity Approach
Abstract The prediction of plastic instability in sheet metals during forming processes represents nowadays an ambitious challenge. To reach this goal, a new numerical approach, based on the loss of ellipticity criterion, is proposed in the present contribution. A polycrystalline model is implemented as a user-material subroutine into the ABAQUS/Implicit fin

12. Yield Surfaces of Material Composed of Porous and Heterogeneous Microstructures Considering Phase Debonding
Abstract This work deals with numerical simulation of the mechanical behavior of materials composed of heterogeneous ductile microstructures using a multi-scale approach considering plasticity processes and phase debonding. Due to few studies about yield surfaces of metal matrix composites (MMC) with weak interfaces presented in the literature, the major goa
