The Theory of Critical Distances to perform the static assessment of 3D-printed concrete weakened by manufacturing defects and cracks [PDF]
, 2022 The Theory of Critical Distances groups together a number of approaches postulating that, in cracked/notched materials subjected to static loading, breakage takes place as soon as a critical length-dependent effective stress exceeds the material tensile ...

Applications of the theory of critical distances in failure analysis [PDF]
Engineering Failure Analysis, 2011 Abstract The Theory of Critical Distances (TCD) is the name which I use to describe a group of methods employed for the prediction of failure in cases where stress concentrations are present and where the failure mode involves cracking, such as fatigue and brittle fracture. Some of these methods are more than 50 years old, some very recent.

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

Geometries of third-row transition-metal complexes from density-functional theory [PDF]
, 2008 A set of 41 metal-ligand bond distances in 25 third-row transition-metal complexes, for which precise structural data are known in the gas phase, is used to assess optimized and zero-point averaged geometries obtained from DFT computations with various ...

Freedom of Speech in the Woke Era: Critical Race Theory and State Neutrality
, 2023 This article considers freedom of speech in light of current debates regarding the banning of symbols some might find offensive and/or hurtful. It considers critical race theory as an example of postmodernism, and its demands for an end to state ...

THEORY OF CRITICAL DISTANCES AND THE THICKNESS OF THE SURFACE LAYER
, 2023 The theory of critical distances is based on the strength of materials L, which is given by its strength properties KIc and σ0. We have shown that the thickness of the surface layer R(I) is equal to the nanocrack length Lnm. We have shown that there is a relationship between L and Lnm: L = 104 Lnm = 104 R(I) ≈ 10-5 М/ρ.

Critical length parameter of HDPE and its use in fatigue lifetime predictions
Fracture and Structural IntegrityThe 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.
