1. Study on elastoplastic coupling mechanics model of the milled mixture of sugar cane
Abstract At present, the phenomenon of elastoplastic coupling isn’t considered in establishing the mechanics model of the milled mixture of sugar cane. In order to describe elastoplastic coupling and yield characteristics, based on uniaxial confined compression tests and direct shear tests, the evolution of the elastic parameters of the solid fiber with v

4. The Search for the Centre of Resistance of a Tooth Using a Finite Element Model and the Continuum Mechanics
Abstract In orthodontics, the CR is defined as the ideal point for the positioning of the bracket. This paper presents numerical analyses of a premolar tooth, which aim at searching the centre of resistance (CR) by applying several external torques. We built the geometry of the tooth by making a tomographic renderisation with the software MIMICS. The numeric

5. Maps of deformations in a cantilever beam using particle image velocimetry (PIV) and speckle patterns
PIV (particle image velocimetry) has been spreading in studies that use the movement of particles to monitor the displacement of an object or the flow of a fluid by means of velocity vectors using optical techniques and second order statistics. PIV is also known as laser speckle velocimetry when associated with speckle patterns. This technique has been used

6. Experimentos de mecánica con temporizador de bajo costo
We have made a mechanical system that consists of a base and a vertical axis that supports a rail. In the ends of the rail two photogates have been prepared. The photogates have been designed and constructed to measure time intervals of rigid solids that move on the rail and that happen for the photogates. The prototype is of low cost and is used for practic

8. Extensiometria óptica por Moiré geométrico digital para anãlise de tensões no plano / Optical extensometry by digital geometric Moiré for in-plane stress analysis
The study of the behavior of building structures pass through the determination of the strain and stresses to evaluate the level of local and global security against the active actions. In the last years in Brazil, the extensometers have been commonly used to measure the strain at a specific single point. The optical extensometry presents itself as an altern

9. Avaliação das distribuições de tensões, por meio da análise de elementos finitos, em uma hemi-maxila, durante a fase de retração anterior por deslizamento, na mecânica ortodôntica / Evaluation of the tensions distributions, using the finite element analysis, in an hemi-maxilla during a sliding anterior retraction , in an orthodontic mechanics
O objetivo deste estudo foi analisar, por meio do método dos elementos finitos, como ocorreram as distribuições de tensões nos dentes, osso e aparelho ortodôntico, durante a fase de retração por deslizamento (150g), em um caso com extrações. Simularam-se duas posições do gancho (mesial e distal de canino), duas alturas do gancho (4 e 9mm) e duas a

10. Experimental investigation on the effects of recycled aggregate on fracture behavior of polymer concrete
The sustainable management of solid wastes stimulates metallurgic and metal mechanics industries to look for safety applications for these wastes. The present paper examines the fracture behavior of polymer concrete (PC) manufactured with recycled foundry waste in substitution of fresh one. The recycled foundry sand is contaminated with polymer resin from th

11. Estrutura e funcionamento dos espermatóforos de Doryteuthis plei (Mollusca: Cephalopoda) e reavaliação da reação espermatofórica dos cefalópodes / Spermatophore structure and functioning in Doryteuthis plei (Mollusca: Cephalopoda), and a reappraisal of the cephalopod spermatophoric reaction
Male coleoid cephalopods produce elaborate spermatophores, which are transferred to the female during mating. These spermatophores are capable of functioning autonomously and extracorporeally, undergoing complicated changes during the so-called spermatophoric reaction, i.e., a complex process of evagination of the spermatophoric tunics and membranes that, ul

12. On numerical solution strategies of contact problems / Sobre estratégias de resolução numérica de problemas de contato
Contact problems represent a class of solid mechanics problems for which the nonlinear behavior is caused by the change of the boundary conditions during the solution process. The present work treats contact problems observing aspects of its formulation and numerical implementation. Specifically, the formulation for two different contact elements is presente
