Physico-Chemical Homogeneization

We propose a numerical framework to simulate the evolution of granular packings driven by surface and volume diffusion. Particle interfaces are captured using an Eulerian level-set approach, enabling a natural treatment of complex topological changes. Coupled with adaptive meshing and parallel computing, the method allows efficient large-scale simulations.

Grains are modeled as elastic,...

Matteo Capoferri (University of Milan)

5/18/26, 1:30 PM

Physico-Chemical Homogeneization

The talk is concerned with the rigorous mathematical description of propagation and localisation of waves in a particular class of composite materials with random microscopic geometry, called micro-resonant (or high-contrast) random media: small inclusions of a “soft" material are randomly dispersed in a “stiff" matrix. The highly contrasting physical properties of the two constituents, ...

Total Sintering and Dense Ceramics

Fabrication of technical ceramics involves three matin steps: synthesis of powder, shaping and sintering. This last step is generally defined as a transformation of compacted powder into a solid with progressive removal of porosity using heat [1]. The driving force of sintering is the reduction of interfaces. It can occur by densification (replacement of solid/vapour interfaces by solid/solid...

Aurélie Chapron (Université de Rouen Normandie)

5/19/26, 11:15 AM

Random Mosaics

In this talk we introduce the Poisson-Voronoi tessellation, a classical model of random mosaic based on seeds placed randomly in the plane, each associated with a Voronoi cell, consisting of all points of the plane closer to that seed than to any other. These cells can be seen as influence zones of the seeds.

The statistical properties of these mosaics (average area, average number of...

Total Sintering and Dense Ceramics

Powder Bed Selective Laser Processing (PBSLP) is a promising technique for the additive manufacturing of alumina. For the method’s success, PBSLP process parameters such as laser power, scanning speed, hatching distance, and scanning strategies need to be investigated. This paper focuses on studying the scanning strategies’ effects on the PBSLP of alumina numerically and experimentally....
