Fusion of Critical Defect Lines in the 2D Ising Model

, 2013
Two defect lines separated by a distance delta look from much larger distances like a single defect. In the critical theory, when all scales are large compared to the cutoff scale, this fusion of defect lines is universal.

Statistical properties of threshold and notch derived estimations of the critical distance according to the line method of the theory of critical distances

International Journal of Fatigue, 2020
Abstract The theory of critical distances is based on the definition of a material-dependent length L. Here, we investigate the statistical properties of L deduced from the crack threshold or a suitable notched specimen geometry. Monte Carlo simulations are done for best-fitting analytical functions to express mean, standard deviation and skewness of

Achieving high performance outcomes through trust in virtual teams [PDF]

, 2009
Developing trust among team members is critical for achieving high performance outcomes. Recently, global business operations necessitated working in a team environment with colleagues outside traditional organizational boundaries, across distances, and ...

Dual theory of the superfluid-Bose glass transition in disordered Bose-Hubbard model in one and two dimensions

, 1998
I study the zero temperature phase transition between superfluid and insulating ground states of the Bose-Hubbard model in a random chemical potential and at large integer average number of particles per site.

A Criterion for Brittle Failure of Rocks Using the Theory of Critical Distances [PDF]

Rock Mechanics and Rock Engineering, 2015
This paper presents a new analytical criterion for brittle failure of rocks and heavily overconsolidated soils. Griffith’s model of a randomly oriented defect under a biaxial stress state is used to keep the criterion simple. The Griffith’s criterion is improved because the maximum tensile strength is not evaluated at the boundary of the defect but at ...

Higgs transitions of spin ice

, 2011
Frustrated magnets such as spin ice exhibit Coulomb phases, where correlations have power-law forms at long distances. Applied perturbations can cause ordering transitions which cannot be described by the usual Landau paradigm, and are instead naturally ...

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 ...
