Probabilistic fatigue assessment of notched components under size effect using critical distance theory

, 2020
Notch features often raise critical influences on fatigue lives of engineering components, which deserve particular attentions for ensuring their structural integrity and reliability.

Lifetime calculation of adhesively bonded joints under proportional and non-proportional multiaxial fatigue loading: a combined critical plane and critical distance approach

The journal of adhesion, 2021
This work presents an approach for lifetime calculation of adhesively bonded joints under proportional and non-proportional multiaxial fatigue loads. In-phase and out-of-phase fatigue data with varying stress ratio (R = 0.1 and −1.0) from several joint ...

Cyclic plastic zone modified critical distance theory for notch fatigue analysis of metals

, 2020
Notch fatigue strength analysis has decisive role in safe structural design and operational reliability of key components. For notched structures, the presence of the cyclic plastic zone (CPZ) is generally cause for crack initiation and growth at the ...

Fatigue Failure Analysis Using the Theory of Critical Distance

Key Engineering Materials, 2011
This 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.

Extending the theory of critical distances to quasi-brittle fracture

Theoretical and Applied Fracture Mechanics, 2021
Abstract 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.

Can Lava Flow Like Water? Assessing Applications of Critical Flow Theory to Channelized Basaltic Lava Flows

Journal of Geophysical Research: Earth Surface, 2022
Flowing lava and water have dramatically different physical properties but can form similar hydraulic structures, including undular hydraulic jumps, or standing wave trains.

Application of the Theory of Critical Distance to Fretting Fatigue

2008
Fretting 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.

Discussion on equivalence of the theory of critical distances and the coupled stress and energy criterion for fatigue limit prediction of notched specimens

, 2020
In the work, analytical expressions for fatigue limit prediction of notched specimen are derived based on the theory of critical distances (PM and LM) and the coupled criterion (PM-FFM and LM-FFM).

Microstructural Parameters in the Theory of Critical Distances

Materials Science Forum, 2007
The 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.
