“Homogenization with non‐homogeneous plastic flow”
International Journal for Numerical and Analytical Methods in Geomechanics, 2023 AbstractThis paper provides the solution of a homogenization model that simultaneously considers the plastic and elastic strain fields in a single analytical formulation. In addition, the authors aim to decouple plastic flows triggered in the inclusions, in the matrix at the interfaces with the inclusions, and in the matrix at a large distance from the

One-step Monte Carlo global homogenization based on RMC code
Nuclear Engineering and Technology, 2019 Due to the limitation of the computers, the conventional homogenization method is based on many assumptions and approximations, and some tough problems such as energy spectrum and boundary condition are faced. To deal with those problems, the Monte Carlo

Functional consequences of the long-term decline of reef-building corals in the Caribbean: evidence of across-reef functional convergence [PDF]
Royal Society Open Science, 2019 Functional integrity on coral reefs is strongly dependent upon coral cover and coral carbonate production rate being sufficient to maintain three-dimensional reef structures.

Physical Review A, 2007 Homogenization protocols model the quantum mechanical evolution of a system to a fixed state independently from its initial configuration by repeatedly coupling it with a collection of identical ancillas. Here we analyze these protocols within the formalism of "relaxing" channels providing an easy to check sufficient condition for homogenization.

Subsampling and homogenization to investigate variability of composite material mechanical properties [PDF]
, 2012 This paper presents an innovative homogenization sampling technique applied to multiscale modelling of composite materials. The goal is to build efficiently statistical variability of mechanical properties at mesoscopic scale from the heterogeneous media

Homogenization of oblique boundary value problems
Advanced Nonlinear Studies, 2023 We consider a nonlinear Neumann problem, with periodic oscillation in the elliptic operator and on the boundary condition. Our focus is on problems posed in half-spaces, but with general normal directions that may not be parallel to the directions of ...

Homogeneous Permutations [PDF]
The Electronic Journal of Combinatorics, 2002 There are just five Fraïssé classes of permutations (apart from the trivial class of permutations of a singleton set); these are the identity permutations, reversing permutations, composites (in either order) of these two classes, and all permutations. The paper also discusses infinite generalisations of permutations, and the connection with Fraïssé's ...

Computational homogenization of nano-materials accounting for size effects via surface elasticity [PDF]
, 2015 The objective of this contribution is to establish a first-order computational homogenization framework for micro-to-macro transitions of porous media that accounts for the size effects through the consideration of surface elasticity at the microscale ...
