Stochastic constitutive model of structural steel based on random field of corrosion depth
Case Studies in Construction Materials, 2022 In this study, a new method based on the random field model (RFM) of corrosion depth was developed to investigate the effect of corrosion randomness on the constitutive relationship of steel.

Hysteresis in the Random Field Ising Model and Bootstrap Percolation [PDF]
, 2002 We study hysteresis in the random-field Ising model with an asymmetric distribution of quenched fields, in the limit of low disorder in two and three dimensions.

Random Field Ising Model and Parisi-Sourlas supersymmetry. Part I. Supersymmetric CFT
Journal of High Energy Physics, 2020 Quenched disorder is very important but notoriously hard. In 1979, Parisi and Sourlas proposed an interesting and powerful conjecture about the infrared fixed points with random field type of disorder: such fixed points should possess an unusual ...

The magnetization-driven random field Ising model at T=0 [PDF]
, 2006 We study the hysteretic evolution of the random field Ising model (RFIM) at T=0 when the magnetization M is controlled externally and the magnetic field H becomes the output variable. The dynamics is a simple modification of the single-spin-flip dynamics

On adaptive refinements in discrete probabilistic fracture models [PDF]
Fracture and Structural Integrity, 2017 The possibility to adaptively change discretization density is a well acknowledged and used feature of many continuum models. It is employed to save computational time and increase solution accuracy.

Multivariate Spartan spatial random field models
Probabilistic Engineering Mechanics, 2014 Abstract This paper introduces a family of stationary multivariate spatial random fields with D scalar components that extend the scalar model of Gibbs random fields with local interactions (i.e., Spartan spatial random fields). We derive permissibility conditions for Spartan multivariate spatial random fields with a specific structure of local ...

Weighted Mean Field Theory for the Random Field Ising Model
, 1994 We consider the mean field theory of the Random Field Ising Model obtained by weighing the many solutions of the mean field equations with Boltzmann-like factors.
