1. XFEM Modelling in Multi-bolted Joints Using a Unified Bolt Preload
Abstract Multi-bolted joints are adopted and designed to provide efficient load transfer within assembled engineering parts. Bearing failure is favorable during design phase due to more progressive failure mode, however, ability of by-pass stress to be transferred to adjacent bolts in multi-bolted joints prone to catastrophic net-tension failure. Former appr

2. Strut-and-tie models for linear and nonlinear behavior of concrete based on topological evolutionary structure optimization (ESO)
Resumo A busca por sistemas resistentes representativos para estrutura de concreto requer profundo conhecimento sobre seu comportamento mecânico. Os modelos de bielas e tirantes são procedimentos clássicos utilizados no dimensionamento do concreto armado onde existem concentrações de tensão, as chamadas regiões descontínuas da estrutura. No entanto,

3. Experimental study of the neighborhood effects on the mean wind loading over two equivalent high-rise buildings
Abstract This paper presents a series of results with respect to the mean values of shear, base moment and torsion acting in a building obtained through an experimental wind tunnel study using the standard building proposed by the Commonwealth Advisory Aeronautical Research Council (CAARC) as building reference. In the loading determination, the interferenc

4. Kinematic and electromyographic analysis of school children gait with and without load in the backpack
AbstractIntroduction: Excessive load on the backpacks can lead to musculoskeletal injuries and gait alterations. The objective of this study was to analyze the electromyographic (EMG) activity in association to the kinematic during the stance and balance phases of gait performed with and without the use of the backpack. Methods Twelve volunteers have execut

5. Functional Characteristics Improvement of Metal Transformable-Volume Structures for Space Applications
ABSTRACT Under conditions of the influence of space environment factors, the thin-walled load-carrying transformable-volume structures are subjected to volumetric deformation and long-time exposure to external loads, close to maximum permissible design values. The required functional properties of transformable-volume structures are ensured on the basis of a

6. The inertial effect of acceleration fields on a self-decoupled wheel force transducer
AbstractWheel force transducer (WFT) is a tool which can measure the three-axis forces and three-axis torques applied to the wheel in vehicle testing applications. However, the transducer is generally mounted on the wheel of a moving vehicle, when abruptly accelerating or braking, the mass/inertia of the transducer itself has extra effects on the sensor resp

7. Stress-based fatigue reliability analysis ofthe rail fastening spring clipunder traffic loads
Nowadays, the rail fastening systems play an important role for preserving the connection between the rails and sleepers in various conditions. In this paper, stress based concept is used to develop a comprehensive approach for fatigue reliability analysisof fastening spring clip. Axle load, speed and material properties are assumed to be random variables. F

9. MicrogeraÃÃo de energia elÃtrica com gÃs de sÃntese de um gaseificador concorrente utilizando ItaÃba mazilaurus / Microgeneration of electricity with syngas from a downtraft gasifier using ItaÃba mazilaurus
The use of biomass as energy source is one of the most promising, because it contributes to reduce emissions of carbon dioxide in the atmosphere and allow the decentralized energy generation. Gasification is a technology of processing biomass energy into a gaseous biofuel of low calorific value. The gas can be used in Otto cycle engine for power generation i
