Microstructural Parameters in the Theory of Critical Distances
Materials Science Forum, 2007The work described below investigates, for the first time, the link between microstructural parameters such as grain size and the length constant L which is known as the critical distance. L is frequently used in the prediction of failure processes such as brittle fracture and fatigue, initiated at stress concentration features such as notches.

The Theory of Critical Distances: A link to micromechanisms
Theoretical and Applied Fracture Mechanics, 2017Abstract The Theory of Critical Distances (TCD) is a methodology for prediction of the effect of stress concentration features on material failure, especially cracking-related mechanisms such as fatigue and brittle fracture. It has a long history but has become much more relevant to industrial problems in recent years thanks to the widespread ...

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.

Fatigue Failure Analysis Using the Theory of Critical Distance
Key Engineering Materials, 2011This paper explores the initial potential of theory of critical distance (TCD) which offers essential fatigue failure prediction in engineering components. The intention is to find the most appropriate TCD approach for a case of multiple stress concentration features in future research.

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.

Fatigue analysis of riveted connections using the theory of critical distances
2021A large number of old metallic bridges have complex riveted details that pose challenges during their fatigue assessment using detail-specific S-N curves. In this paper, the fatigue life prediction capability of a novel method, the Theory of Critical Distances (TCD), which relies on the fatigue properties of the plain material only is investigated ...

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 ...

Analysis of fatigue failures in components using the theory of critical distances
Engineering Failure Analysis, 2005Abstract This paper explores the use of the theory of critical distances (TCD) in the prediction of high-cycle fatigue behaviour in engineering components. Theories of this type have been in use for over 50 years in various forms, and recently have been brought up to date by linking them with linear elastic fracture mechanics (LEFM).
