Using porous random fields to predict the elastic modulus of unoxidized and oxidized superfine graphite

open access: yesMaterials & Design, 2022
Nuclear graphite is a candidate material for Generation IV nuclear power plants. Porous materials such as graphite can contain complex networks of pores that influence the material's mechanical and irradiation response.

Evolving Surface Finite Element Methods for Random Advection-Diffusion Equations [PDF]

open access: yesSIAM/ASA Journal on Uncertainty Quantification, 2018
In this paper, we introduce and analyse a surface finite element discretization of advection-diffusion equations with uncertain coefficients on evolving hypersurfaces. After stating unique solvability of the resulting semi-discrete problem, we prove optimal error bounds for the semi-discrete solution and Monte Carlo samplings of its expectation in ...

Randomized Sampling for Basis Function Construction in Generalized Finite Element Methods

open access: yesMultiscale Modeling & Simulation, 2020
In the framework of generalized finite element methods for elliptic equations with rough coefficients, efficiency and accuracy of the numerical method depend critically on the use of appropriate basis functions. This work explores several random sampling strategies that construct approximations to the optimal set of basis functions of a given dimension,

Transformation Methods for Static Field Problems With Random Domains [PDF]

open access: yes, 2011
The numerical solution of partial differential equations onto random domains can be done by using a mapping transforming this random domain into a deterministic domain. The issue is then to determine this one to one random mapping.

Discrete element method to simulate continuous material by using the cohesive beam model [PDF]

open access: yes, 2012
The mechanical behavior of materials is usually simulated by the continuous mechanics approach. However, simulation of non-continuous phenomena like multi fracturing is not well adapted to a continuous description.
