Analysis of pulsatile flow in arteriovenous fistula through numerical simulation
(Universidade Federal do Rio Grande do NorteBrasilUFRNEngenharia Mecânica, 2018-06-28)
This work aim to analyze the hemodynamic factors in the flow within an Arteriovenous Fistula (AVF) using a flow field calculated by numerical simulation as a visualization technique. The geometrical model is virtually ...
THE PHOTOELASTIC ANALISYS OF VERTEBRAL FIXATION SYSTEM SCREWS
(ATHA COMUNICACAO & EDITORA, 2009)
Introduction: The photoelasticity is used for assessing the tensions/deformations involved in photoelastic materials when submitted to a given load by the observation of optical effects. The screw performance and mechanical ...
Finite element analysis of bonded model Class I 'restorations' after shrinkage
(ELSEVIER SCI LTDOXFORD, 2012)
Objectives. The C-Factor has been used widely to rationalize the changes in shrinkage stress occurring at the tooth/resin-composite interfaces. Experimentally, such stresses have been measured in a uniaxial direction between ...
Polymerization Shrinkage and Push-out Bond Strength of Different Composite Resins for Sealing the Screw-access Hole on Implant-supported Crowns
(2020-01-01)
Purpose: To evaluate the effect of composite resin polymerization shrinkage stress on the stress distribution in the implant-supported crown-access hole, and on the bond strength between the ceramic and composite resin. ...
Proposição de uma metodologia preditiva para avaliação do efeito caking em diferentes tipos de açúcares comerciais
(2020-03-23)
Este trabalho apresenta os resultados preliminares de uma metodologia experimental alternativa em desenvolvimento para se prever o efeito caking comumente observados em materiais particulados durante o seu período de ...
Numerical simulation of a submerged circular turbulent jet impinging on flat and eroded boundaries
(CRC PRESS/BALKEMA, 2018)
A numerical and analytical study of the stress field generated by the contact between a rail and a wheel
(Springer, 2020-06-19)
This article presents a study of the contact stresses between a rail and a wheel, in order to understand the mechanism related to this application. When two bodies, regardless of their forms, touch each other due to an ...
