Ligações com tubos galvanizados em madeira laminada colada de eucalipto grandis, solicitadas a momento fletor e força cortante
(Universidade Federal de Minas GeraisUFMG, 1999-12-28)
This Dissertation is about an experimental study made in Eucalyptus Grandis laminated timber connections under combined efforts (bending moment and shearing force) to determine these connections rigidity.The bending tests ...
Damping behavior of continuous fiber/metal composite materials by the free vibration method
(Elsevier B.V., 2006-01-01)
Fiber metal laminates (FML) offer significant improvements over current available materials for aircraft structures due to their excellent mechanical characteristics and relatively low density. Non-destructive testing ...
Quantitative microscopy characterization of hydrous niobium phosphate into bleached cellulose
(Pergamon-Elsevier B.V. Ltd, 2010-07-01)
In this research the spatial distribution characterization of niobium phosphate into bleached cellulose was carried out combining processing and images analysis obtained by SEM and statistical methodologies. The objective ...
Fatigue Behavior of Weld Repaired AISI 4130 Aeronautic Steel Used in Critical Flight Safety Structures
(Trans Tech Publications Ltd, 2014-01-01)
Since the 1950s, fatigue is the most important project and operational consideration for both civil and military aircrafts. For some aircraft models the most loaded component is one that supports the motor: the Motor Cradle. ...
Implementation of an Induction Motor Mathematical Model for Stator Winding Fault Analysis
(Ieee, 2018-01-01)
Induction motors are versatile, affordable and highly efficient machines, which makes them the principal source of electromechanical power in industrial application. However, induction motors eventually undergo failures, ...

Comparative analysis of signal processing techniques for impedance-based SHM applications in noisy environments
(2019-07-01)
Structural health monitoring (SHM) systems have been extensively studied in recent decades to determine the health statuses of mechanical, naval and aerospace engineering components. Currently, one of the most promising ...
Conservation implications of behavioural interactions between the Giant African Snail and a Native Brazilian species
(Taylor & Francis Ltd, 2017-05-01)
The Giant African Snail Achatina fulica is widely considered one of the most invasive species in the world. Megalobulimus paranaguensis is a snail endemic to the Brazilian Atlantic Rainforest. Data on possible interactions ...
Acceleration in germination sensu stricto plays a central role on seedling vigor in post-germination
(2021-10-01)
An obvious relationship between germination sensu stricto and seedling development during post-germination has been considered, but not explained concerning vigor. Taking this into account, we used measurements of water ...
Uncertainty on measurement of elastomemeric isolators effective properties
(2021)
Elastomeric isolators are subjected to a series of non-destructive tests with several repeated deformation cycles. For each cycle, effective properties are calculated and afterward averaged. Despite their variability, and ...
