Influence of Different Fibreglass Post Geometries on the Stress Distribution and Pull-Out Bond Strength Before and After Mechanical Cycling
(2021-01-01)
Objective: There are no reports in the literature on whether FGP geometry influences the bond strength of the endodontically restored tooth. This study aimed to determine the stress distribution and the pull-out bond ...
Estimation of reliability of multicomponent stress-strength of a bathtub shape or increasing failure rate function
(Emerald Group Publishing Ltd, 2019-02-04)
Purpose The purpose of this paper is to deal with the Bayesian and non-Bayesian estimation methods of multicomponent stress-strength reliability by assuming the Chen distribution. Design/methodology/approach The reliability ...
Strength prediction of squat structural walls via calibration of a shear-flexure interaction model
(ELSEVIER, 2010)
This study deals with a modeling approach that integrates shear and flexure interaction to predict the response
of reinforced concrete squat walls. The model incorporates RC panel behavior into a displacementbased
column ...
Stress-Strength Reliability Analysis with Extreme Values based on q-Exponential Distribution
(Wiley, 2017)
When dealing with practical problems of stress-strength reliability, one can work with fatigue life data and make use of the well-known relation between stress and cycles until failure. For some materials, this kind of ...
Planejamento multiobjetivo otimizado de recursos energéticos distribuídos aplicando o método strength pareto evolutionary algorithm 2
(Universidade Federal de Santa MariaBrasilEngenharia ElétricaUFSMPrograma de Pós-Graduação em Engenharia ElétricaCentro de Tecnologia, 2020-08-07)
The diffusion of distributed energy resources (DER) in the electric energy distribution systems in Brazil, outcomes in the perception, through the Electric Sector agents, of a set of benefits that these technologies promote ...
Properties of compacted copper fibre reinforced cement composite
(1985)
This paper presents the properties of a new fibre cement material formed by short ductile copper fibres randomly distributed in portland cement paste and compacted by compression to 35 MPa. The optimum percentage and the ...
ALTERNATIVE MODEL TO DETERMINE THE CHARACTERISTIC STRENGTH VALUE OF WOOD IN THE COMPRESSION PARALLEL TO THE GRAIN
(Univ Bio-bio, 2020-07-01)
Wood strength values are calculated based on the characteristic value, which corresponds to the 5 % percentile of a given probability distribution model. For a few number of samples (12 samples), the Brazilian standard ...
Benchmark regulation and efficiency of electricity distribution: strengths and weaknesses
(IEEE, 2007)
A growing challenge in the restructuring of the electrical sector, where competition is introduced in the generation area, is to achieve equivalent efficiencies in the electrical distribution service, an activity that ...
Seismic behavior of squat reinforced concrete shear walls
(EARTHQUAKE ENGINEERING RESEARCH INSTITUTE, 2002)
The behavior of reinforced concrete walls that exhibit the shear mode of failure is studied, through the results of an experimental program that included the test of 26 full-scale specimens subjected to cyclic horizontal ...
