Abstract
Foams, like most highly structural fluids, exhibit rheological behavior that is both fascinating and complex. We have developed microheological models for uniazial extension and simple shearing flow of a 'dry' perfectly ordered, three-dimensional foam composed of thin films with uniform surface tension T and negligible liquid content. We neglect viscous flow in the thin films and examine large elastic-plastic deformations of the foam.
