Scale-adaptive simulation of unsteady cavitation around a naca66 hydrofoil [PDF]

, 2019
Distances between consecutive aftershocks are analysed by means of mono- and multifractal theory with the aim of quantifying the complexity of the physical mechanism governing them, as well as their predictability and predictive instability.

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

Fracture 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.

The Spacetime Life of a Non-BPS D-particle [PDF]

, 2000
We investigate the classical geometry generated by a stable non-BPS D-particle. We consider the boundary state of a stable non-BPS D-particle in the covariant formalism in the type IIB theory orbifolded by (-1)^{F_L} I_4.

The Theory of Critical Distances applied to multiscale toughening mechanisms [PDF]

Engineering Fracture Mechanics, 2019
Abstract The Theory of Critical Distances (TCD) is an approach used for predicting the effect of cracks and notches on fracture and fatigue behaviour. In recent years it has been successfully applied to a wide range of problems across all classes of materials.

Low x Scattering as a Critical Phenomenon [PDF]

, 2001
We discuss deep inelastic scattering at low $x$ as a critical phenomenon in 2+1 space-time dimensions. QCD (SU2) near the light cone becomes a critical theory in the limit of $\lim x \to 0$ with a correlation mass $m(x) \propto x^{\nu/2}$.

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.

Biomimetics Design of Tooth Root Zone at Cylindrical Gears Profile

Biomimetics, 2023
During the last few decades, the requirements for modern machine elements in terms of size reduction, increasing the energy efficiency, and a higher load capacity of standard and non-standard gears have been very prevalent issues.

A Study of Finite Temperature Gauge Theory in (2+1) Dimensions [PDF]

, 1996
We determine the critical couplings and the critical exponents of the finite temperature transition in SU(2) and SU(3) pure gauge theory in (2+1) dimensions.

On Supergravity Solutions of Branes in Melvin Universes

, 2005
We study supergravity solutions of type II branes wrapping a Melvin universe. These solutions provide the gravity description of non-commutative field theories with non-constant non-commutative parameter.
