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

open access: yesFracture 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.

The application of the Theory of Critical Distances to nonhomogeneous materials

open access: yesFatigue & Fracture of Engineering Materials & Structures, 2023
AbstractThe Theory of Critical Distances (TCD) has undoubtedly represented a breakthrough in the brittle failure assessment of engineering materials containing defects, crack, or notches. The basic idea on which the simplest formulation of the TCD is based is to evaluate an effective stress at a characteristic distance from the tip of the defect/crack ...

Critical length parameter of HDPE and its use in fatigue lifetime predictions

open access: yesFracture and Structural Integrity
The contribution describes the fatigue lifetime predictions of polyethylene notched specimens based on the theory of critical distance. The approach uses the line method, which averages the axial stress over the critical distance.

Comparing distance bounding protocols: A critical mission supported by decision theory [PDF]

open access: yesComputer Communications, 2015
Distance bounding protocols are security countermeasures designed to thwart relay attacks. Such attacks consist in relaying messages exchanged between two parties, making them believe they communicate directly with each other. Although distance bounding protocols have existed since the early nineties, this research topic resurrected with the deployment

Combined notch and size effect modeling of metallic materials for LCF using plasticity reformulated critical distance theory

open access: yesJournal of Materials Research and Technology, 2022
Fatigue assessment of notched parts plays imperative performance in structural integrity and reliability of major equipment. The theory of critical distance (TCD) involves determining the fatigue strength of notched parts from the linear elastic stress ...
