Comparison of local fatigue assessment methods for high-quality butt-welded joints made of high-strength steel

Forces in Mechanics, 2022
Fatigue strength of welded joints is typically independent of the parent material static strength; however, there are two exceptions from this rule—post-weld treated joints and high-quality joints.

Duality of singularities of multiscale damage localization and crack advance: length variety in Theory of Critical Distances

Fracture and Structural Integrity, 2019
The existence of two singularities related to the stress field at the crack tip and blow-up kinetics of damage localization is considered as the physical basis for the interpretation of the Theory of Critical Distances.

Environmentally Assisted Cracking Behavior of S420 and X80 Steels Containing U-notches at Two Different Cathodic Polarization Levels: An Approach from the Theory of Critical Distances

Metals, 2019
This paper analyzes, using the theory of critical distances, the environmentally assisted cracking behavior of two steels (S420 and API X80) subjected to two different aggressive environments.

Some Applications of Critical Point Theory of Distance Functions on Riemannian Manifolds [PDF]

Compositio Mathematica, 2002
In this paper, we use the theory of critical points of distance functions to study the rigidity and topology of Riemannian manifolds with sectional curvature bounded below. We prove that an n -dimensional complete connected Riemannian manifold M with ...

Multiaxial fatigue life assessment of dental implants

Heliyon
As screwed joints, dental restorations may suffer mechanical failures such as screw loosening and implant or prosthetic screw failure due to fatigue. This work is focused on the failure of the implant and develops a numerical methodology to predict its ...

Estimation of Fracture Loads in AL7075-T651 Notched Specimens Using the Equivalent Material Concept Combined with the Strain Energy Density Criterion and with the Theory of Critical Distances

Metals, 2018
The main goal of this paper is the application of the Strain Energy Density (SED) criterion and the Theory of Critical Distances (TCD), both of them in combination with the Equivalent Material Concept (EMC), to predict the fracture loads of aluminum ...

Fatigue Life Prediction of Pump Head Materials Based on the Theory of Critical Distances

Shiyou jixie, 2020
To study whether the critical distance theory can reasonably predict the fatigue life of a notched specimen, the finite element model for the chrome-nickel alloy notched specimen of a certain pump head material was established, and the linear elastic ...

On the application of the Theory of Critical Distances for prediction of fracture in fibre composites [PDF]

Fracture and Structural Integrity, 2010
This paper is concerned with the fracture of composite materials containing stress concentration features such as notches and holes. In particular, it addresses the question of the use of the Theory of Critical Distances (TCD) – a method which is widely ...

De Husserl à Sartre. La structure intentionnelle de l’image dans L’Imagination et L’Imaginaire

Methodos, 2012
Sartre’s two books about the image are difficult to interpret, even it is rarely noticed. Indeed the first book, L’Imagination, ends with a glowing tribute to the Husserlian theory of image. The second one, L’Imaginaire, initially combined with the firth
