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.

    Vendredi 31 mai de 11h00 à 12h00 - Salle réunion PMMH 1
    Earthquake statistical properties : an explanation for the distribution of magnitude and for the existence of aftershocks
    Earthquakes in nature follow several statistical properties. In particular, the distribution of energy released by an earthquake (Gutenberg-Richter's law) and the frequency of aftershocks after a large event (Omori's law) are both power-laws. By studying several earthquake models, we have shown that the (...)

    A hydrodynamic analog of critical phenomena : an uncountably infinite number of universality classes
    When a solid object starts falling into a viscous fluid from air-liquid interface, air is entrained into the liquid and eventually detaches from the solid. Such detachment could occur with or without topological change. Recently, it was found that the former case (i.e., breakup, a form of singular transitions) is (...)

    1D confinement controls cell shape and migration
    Pericytes are mural cells of the microvasculature, they wrap around small vessels, support the vessels mechanically and participate in blood flow regulation. Pericytes are distinguished by two main characteristics ; first their distinct morphology, which has been likened to a “bump on a log”, as they present long (...)

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.
