Tensoes Residuais na Soldagem, Aspectos Basicos
(1995-12-01)
The purpose of this paper is to analyze the basic aspects of the residual stresses in welding. Concepts about macro and micro residual stresses in metals are considered in welding. In a simple welding model is shown how ...
Stress analysis in oral obturator prostheses: Imaging photoelastic
(2013-07-08)
Maxillary defects resulting from cancer, trauma, and congenital malformation affect the chewing efficiency and retention of dentures in these patients. The use of implant-retained palatal obturator dentures has improved ...
Finite-Element Analysis of Stress on Dental Implant Prosthesis
(WILEY-BLACKWELL, 2010)
Background: Understanding how clinical variables affect stress distribution facilitates optimal prosthesis design and fabrication and may lead to a decrease in mechanical failures as well as improve implant longevity. ...
Finite-Element Analysis of Stress on Dental Implant Prosthesis
(Wiley-Blackwell, 2010-01-01)
Background:Understanding how clinical variables affect stress distribution facilitates optimal prosthesis design and fabrication and may lead to a decrease in mechanical failures as well as improve implant longevity.Purpose:In ...
Use of Stress Analysis Methods to Evaluate the Biomechanics of Oral Rehabilitation With Implants
(Allen Press Inc, 2014-04-01)
Because the biomechanical behavior of dental implants is different from that of natural tooth, clinical problems may occur. The mechanism of stress distribution and load transfer to the implant/bone interface is a critical ...
Influence of the degradation on the stress cracking values of high density polyethylene (HDPE) geomembranes after different exposures
(2012-12-03)
This paper presents results from stress cracking (SC) tests performed in both fresh and exposed high density polyethylene (HDPE) geomembranes (GM). The HDPE GMs were exposed to ultraviolet radiation, thermal aging (air ...
Stress distribution in the peri-implant area of pure titanium and titanium-zirconium small implants
(2019-01-01)
Aim: In dental implant treatment, there is a demand for mechanically stronger implants. Despite the existence of several studies showing the clinical success of narrow diameter implants, most of them are based on pure ...
Green Brazilian propolis action on macrophages and lymphoid organs of chronically stressed mice
(Oxford University Press, 2008-03-01)
Stress is a generic term that summarizes how psychosocial and environmental factors influence physical and mental well-being. The interaction between stress and immunity has been widely investigated, involving the ...
Numerical analysis of the influence of film thickness and properties on the stress state of thin film-coated piston rings under contact loads
In this work, a series of finite element analyses was conducted to analyze the stresses in thin film-coated piston rings under contact loads. The actual normal and tangential pressure observed during a complete four-stroke ...
The effect of resection angle on stress distribution after root-end surgery
(2018-03-01)
Introduction: This study aimed to investigate the influence of the resection angle on the stress distribution of retrograde endodontic treated maxillary incisors under oblique-load application. Methods and Materials: A ...
