The theory of critical distances: a review of its applications in fatigue
Engineering Fracture Mechanics, 2008Abstract This paper attempts to review the most interesting findings in the use of the theory of critical distances (TCD) to predict fatigue strength of notched mechanical components. Initially, the most modern formalisations of the TCD are considered, showing their peculiarities and differences.

Implementation of the Theory of Critical Distances using mesh control
Theoretical and Applied Fracture Mechanics, 2017Abstract The Theory of Critical Distances (TCD) is a method for predicting fatigue and fracture at stress concentration features. It is extensively used in the design of engineering components, being a relatively simple approach based on post processing of finite element analysis (FEA).

On the use of the theory of critical distances with mesh control for fretting fatigue lifetime assessment [PDF]
Tribology International, 2020 This work analyses the viability of the theory of critical distances (TCD) using mesh control for fretting fatigue lifetime assessment. More than seven hundred sets of simulations were performed by taking seventy different experimental tests reported previously in the literature.

Analysis of notch effect in PMMA using the Theory of Critical Distances
Engineering Fracture Mechanics, 2012Abstract The Theory of Critical Distances is actually a group of methodologies, all of them using a characteristic material length parameter when performing fracture assessments on any kind of stress risers. In this paper, the application of the Theory of Critical Distances on Polymethyl methacrylate is analysed, the parameters involved in the ...

Engineering Fracture Mechanics, 2010
Abstract The present technical note is concerned with the use of the Theory of Critical Distances, applied in the form of the Point Method, to estimate the range of the threshold value of the stress intensity factor, Δ K th , as well as the plane strain fracture toughness, K Ic , of conventional engineering materials.

A Critical Analysis of Transactional Distance Theory
Quarterly Review of Distance Education, 2005This investigation reviews published empirical studies that attempted to support or to validate transactional distance theory (Moore, 1993). It was found that either data only partially supported the theory or, that if they apparently did so, the studies lacked reliability, construct validity, or both.

Application of the Theory of Critical Distance to Fretting Fatigue
2008Fretting fatigue occurs at the contact interface of mechanical joints which are designed to be at rest but that nevertheless experience some sort of relative movement due to vibration. This work aims to develop a crack initiation threshold condition for fretting fatigue.

Extending the theory of critical distances to quasi-brittle fracture
Theoretical and Applied Fracture Mechanics, 2021Abstract The results of theoretical and experimental studies of brittle and quasi-brittle fracture of plaster plates containing a circular hole and subjected to non-uniformly distributed compression are presented. This paper summarizes the results, partially published by the author earlier.
