Study of abrasive cutting of natural quartz for manufacturing piezoelectric power generators
(Materials Science Forum, 2018-01-01) [Trabalho apresentado em evento]
The present study is related with the dicing of natural quartz crystals as part of the process manufacturing of a power generator device. Power generation is important, mainly for wifi systems, which use of batteries is ...
Modelling the 3D Crack Network Observed in Desiccated Soils
(Panam Unsaturated Soils 2017: Swell-shrink And Tropical Soils, 2018-01-01) [Trabalho apresentado em evento]
The study of crack generation and propagation in soils is a very complex problem and possesses several challenges. In this paper a novel approach is proposed to model the formation and propagation of cracks in drying soils. ...
Wheel wear and workpiece surface analyses after grinding hardened steel with minimum quantity lubrication technique assisted with wheel cleaning jet (MQL-AWCJ)
(73rd Society of Tribologists and Lubrication Engineers Annual Meeting and Exhibition 2018, 2018-01-01) [Trabalho apresentado em evento]
Minimum Quantity Lubrication (MQL) technique has been consolidated in the machining processes as an alternative to conventional technique because of its cleaner production characteristics. However, for grinding process ...
A Performance Evaluation of Electromagnetic Time Reversal Method for Locating Faults in Branched Cable Networks
(2018 13th Ieee International Conference On Industry Applications (induscon), 2018-01-01) [Trabalho apresentado em evento]
The post-failure impedance estimative method is one of the most used ways to locate faults in distribution systems. However, the presence of the distributed generation can degrade the precision of this kind of procedure. ...
Multiscale modeling of steel fiber reinforced concrete based on the use of coupling finite elements and mesh fragmentation technique
(Computational Modelling Of Concrete Structures. Euro-c 2018, 2018-01-01) [Trabalho apresentado em evento]
A multiscale model is proposed based on the use of coupling finite elements recently developed by the authors. This feature allows the use of the same strategy to deal with two problems of non-matching meshes addressed in ...
An adaptive concurrent two-scale FE model to predicting crack propagation in concrete
(Computational Modelling Of Concrete Structures. Euro-c 2018, 2018-01-01) [Trabalho apresentado em evento]
Finite element analysis including explicitly the details of the heterogeneities (finer-scale) can dramatically increase the numerical effort and memory demand. To minimize these drawbacks, a new concurrent adaptive multiscale ...
