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 ...
Validation of Performance-Dependent Failure Criterion for Concretes
(American Concrete Institute, 2011-05)
This paper focuses on the reformulation of the internal functions of the performance-dependent failure criterion (PDFC) for concrete, proposed by the authors, and its validation for different concrete qualities and stress ...
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 ...

Effects of nitriding and shot peening treatments and stress concentration on the fatigue strength of AISI 4340 steel
(2001-01-01)
Nitriding is a thermochemical surface treatment applied to improve the fatigue and wear resistances of mechanical components. Shot peening is a cold work process in which small spheres impact the surface of a piece, producing ...
Adhesive cementation of zirconia posts to root dentin: Evaluation of the mechanical cycling effect
(2008-12-01)
This study evaluated the effect of mechanical cycling on the bond strength of zirconia posts to root dentin. Thirty single-rooted human teeth were transversally sectioned to a length of 16 mm. The canal preparation was ...
