Séminaire PMMH - Olivier Plé (LOCIE-CNRS)

Vendredi 5 avril de 11h00 à 12h00 - Salle réunion PMMH 1

Rammed earth : A complex medium

Rammed earth is a complex material which is attractive nowadays in construction because of its small environmental footprint. However, this material has specific characteristics, especially : its sensitivity to water, its low mechanical static capacity but a fairly good seismic performance, its high thermal conductivity which cannot guarantee sufficient winter comfort, its high heterogeneity which makes it a size effect material….. In short, a complex, unsaturated heterogeneous material with numerous couplings.
In this presentation I will try to show the complexity of the material and how physics helps us to understand for a better use in construction.

    Drops with deformable boundaries : Flat tops, Locomotion and Ageing
    A liquid droplet placed on a rigid, planar surface has a captivating simplicity : its surface is a spherical cap and remains in equilibrium. In this talk, I'll show that the addition of a deformable boundary leads to a range of new phenomena : evaporating droplets with an elastic skin may develop flat tops, while (...)

    The co-moving velocity, a new concept in immiscible two-phase flow in porous media Alex Hansen PoreLab, Department of Physics, NTNU, Trondheim, Norway Since 1936, relative permeability theory has been the leading description of immiscible two-phase flow in porous media at scales much larger than the pore scale. (...)

    Emergence of spontaneous collective oscillations in dense Human crowds
    Massive crowd gatherings form some of the most dangerous and unpredictable environments [1]. However, we lack quantitative characterizations of their dynamics and the heuristic principles used to explain and predict their motion remain elusive. In this talk, I will present our analysis of the dynamics of thousands (...)
Information for the speakers

The audience is composed of people with rather heterogeneous backgrounds including specialists in solids, fluids, granular flows, statistical physics... so the idea is to keep your talk understandable by people not necessarily working in your field... The seminar time slot runs from 11am to noon so the best is to make the talk last around 45 minutes to leave some time for discussion.
