Kabla, A and Debrégeas, G (2003) Local stress relaxation and shear banding in a dry foam under shear. Phys Rev Lett, 90. 258303-. ISSN 0031-9007Full text not available from this repository.
We have developed a realistic simulation of 2D dry foams under quasistatic shear. After a short transient, a shear-banding instability is observed. These results are compared with measurements obtained on real 2D (confined) foams. The numerical model allows us to exhibit the mechanical response of the material to a single plastication event. From the analysis of this elastic propagator, we propose a scenario for the onset and stability of the flow localization process in foams, which should remain valid for most athermal amorphous systems under creep flow.
