Bond tests and on-site structural concrete quality control
(2010-01-01)
Quality control of structural concrete has been conducted for decades using the axial compression test. The Pull-Out Bond test is suggested here as an alternative to the axial compression test of concrete. Well known and ...
Soil stabilization studying of tropical brazilian soil by unconfined strength compression tests
(2007-01-01)
The tropical soils exhibit a unique mechanical behavior due to their genesis, with a partially saturated condition, and are very dependent on the degree of weathering. The term tropical soil includes both lateritic and ...
Natural fiber reinforced unsaturated polyester composites - An approach on compression molding
(2001-12-01)
This work has been performed at Tapetes Sao Carlos-Brazil with the cooperation of the DaimlerChrysler Research Center Team in Ulm - Germany. The objective of the present paper is to report the results obtained with natural ...
Influence of different drying methods on tbe rheological properties of raisins
(Isnt Tecnologico Veracruz, 2001-01-01)
The rheological parameters of raisins were obtained after three different drying methods: convective, osmo-convective and solar drying. Compression tests were applied to rehydrated samples by using a Texture Analyzer TAXT2i. ...
Compressive fatigue in titanium dental implants submitted to fluoride ions action
(2007-07-01)
The aim of this study was to assess the influence of a fluoridated medium on the mechanical properties of an internal hexagon implant-abutment set, by means of compression, mechanical cycling and metallographic characterization ...
Shear modulus G(0) and its correlations with matric suction, unconfined compression strength and tensile strength of an unsaturated residual soil
(Ios Press, 2015-01-01)
Several studies have been developed aiming to understand the behavior of saturated natural soils under small strains. A few studies have considered unsaturated soils, in most cases compacted soils and, eventually, disregarding ...
Wavepackets in Boundary Layers Close to Transonic Speeds
(2015-01-01)
In practical situations, natural transition determines the transition to turbulence process. Experimental evidence suggest that the wave packet evolution is related closely to natural transition. The major part of numerical ...
Mechanical behavior of isolated intervertebral disc
(2009-12-01)
The study on several components of intervertebral joints is essential to understand the spine's degenerative mechanisms and to assess the best method for their treatment. For such study it is necessary to know the mechanical ...
A finite element approach for predicting the ultimate rotation capacity of RC beams
(2013-07-15)
This paper presents a numerical approach to model the complex failure mechanisms that define the ultimate rotational capacity of reinforced concrete beams. The behavior in tension and compression is described by a constitutive ...
Spent FCC catalyst for preparing alkali-activated binders: An opportunity for a high-degree valorizatio
(2014-01-01)
Spent FCC catalyst is a waste from the petrochemical industry which has excellent pozzolanic properties, containing more than 90% silica and alumina. Its similarity to metakaolin creates interesting prospects for its use ...
