【 摘 要 】

The authors define in 2D random foam the mesoscopic stress and strain, which can be directly measured from a foam picture. They evaluate the mesoscopic definition in static foams. Comparing the shearing flow of monodispersed and polydispersed foams, we discuss the stress-strain relationship in the elastic regime and the transition between the elastic and the viscous regimes.
