Together with our post-doctoral fellow Othmane Zerhouni, my colleague Kostas Danas (LMS, École polytechnique) and I have recently published a new paper in International Journal of Engineering Science. The paper is titled “Quantifying the effect of two-point correlations on the effective elasticity of specific classes of random porous materials with …

I recently had the pleasure to give a talk on “Variational estimates of the poroelastic coefficients” at the 6th Biot Conference on Poromechanics that took place at École des Ponts ParisTech on July 9-13, 2017. This is joint work with my colleague Siavash GHABEZLOO. It has been ongoing for years …

My student Mohamed Hassan Khalili has recently had one of his papers published in Physical Review E. The paper is called “A numerical study of one-dimensional compression of granular materials”. I have only been very marginally involved in this DEM study, which is divided in two parts.

Part I is …

Our paper “Discrete Digital Projections Correlation: a reconstruction-free method to quantify local kinematics in granular media by X-ray tomography” has recently been published in Experimental Mechanics. The abstract is reproduced below

We propose a new method to measure the translations and rotations of each individual grain in a granular material …

My paper “Towards improved Hashin--Shtrikman bounds on the effective moduli of random composites” has recently been published in Mechanics & Industry. The abstract is reproduced below

The celebrated bounds of Hashin and Shtrikman on the effective properties of composites are valid for a very wide class of materials. However, they incorporate …

My paper “Reconstructing displacements from the solution to the periodic Lippmann--Schwinger equation discretized on a uniform grid” has recently been published in International Journal of Numerical Methods in Engineering. The abstract is reproduced below

Uniform grid solvers of the periodic Lippmann--Schwinger equation have been introduced by Moulinec and Suquet for …

My student Vinh Phuc Tran has recently had one of his papers published in Mechanics of Materials. The paper is called Stochastic modeling of mesoscopic elasticity random field. The abstract is reproduced below

In the homogenization setting, the effective properties of a heterogeneous material can be retrieved from the solution …

One of my manuscripts has just been accepted for publication in the International Journal of Solids and Structures. It is called A variational form of the equivalent inclusion method for numerical homogenization. The abstract is reproduced below

Due to its relatively low computational cost, the equivalent inclusion method is an …

It is my pleasure to announce that one of my papers has recently been accepted for publication in the Journal of the Mechanics and Physics of Solids. It's called New boundary conditions for the computation of the apparent stiffness of statistical volume elements.

It introduces a new set of boundary …
