Liquid foams exhibit interesting mechanical properties exploited by food, cosmetic or oil industries. They are easy to produce ; their structure is mainly made of gas bubbles dispersed inside a continuous liquid phase and stabilized by surfactants. This multiphasic feature leads to a two-fold rheological behavior : liquid foams behave as solids when submitted to small stresses and flow like liquids above a yield stress. While classical rheometry aims at characterizing the macroscopic behavior of materials such as foams, our goal is to link the macroscopic scale with the local mechanisms that are in interplay at the bubble scale : deformation, rearrangement, liquid flow and dissipation. The "Liquid Foams" project developed at our institute is divided into three parts and tackled with several methods.
