Probabilistic machine learning for detection of tightening torque in bolted joints
(2022-01-01)
Observing the loss of tightening torque using modal parameters is challenging due to the variability and nonlinear effects in bolted joints. Thus, this paper proposes a combined application of two probabilistic machine ...
Modeling stick-slip in bolted joint tightening process
(2020-04-09)
Stick-slip affects torque-preload relationship during bolted joint tightening process. Its occurrence is not always possible to avoid and it can lead to an unreliable joint. In this study, tightening process was investigated ...

Implant Abutment Deformation During Prosthetic Cylinder Screw Tightening: An In Vitro Study
(QUINTESSENCE PUBLISHING CO INC, 2009)
Purpose: Nonpassive fit frameworks are believed to lead to implant overload and consequently loss of osseointegration. This is one of the most commonly reported failures of implant prostheses. In an ideal situation of ...
Implant abutment deformation during prosthetic cylinder screw tightening: An in vitro study

Purpose: Nonpassive fit frameworks are believed to lead to implant overload and consequently loss of osseointegration. This is one of the most commonly reported failures of implant prostheses. In an ideal situation of ...
Good practices for designing and experimental testing of dynamically excited jointed structures: The Orion beam
(Elsevier B.V., 2021-06-30)
This paper proposes a new lap-joint configuration, the so-called Orion beam. The new setup is composed of two thin beams connected by three bolted joints with contact patches on each connecting bolt. The Orion beam suggests ...
Loosening Torque Of Universal Abutment Screws After Cyclic Loading: Influence Of Tightening Technique And Screw Coating
(KOREAN ACAD PROSTHODONTICSSEOUL, 2015)
Influence of repeated screw tightening on bacterial leakage along the implant-abutment interface
(WILEY-BLACKWELL PUBLISHING, INC, 2009)
Objectives Bacterial penetration along the implant-abutment interface as a consequence of abutment screw loosening has been reported in a number of recent studies. The aim of this in vitro study was to investigate the ...
Tightened Lieb-Oxford Bound for Systems of Fixed Particle Number
(AMER CHEMICAL SOC, 2009)
The Lieb-Oxford bound is a constraint upon approximate exchange-correlation functionals. We explore a nonempirical tightening of that bound in both universal and electron number-dependent form. The test functional is PBE. ...
