Mechanics of Interfacial Composite Materials
[Under construction -- Nick Schade (fall 2009)]
Experiments have shown that if a fluid-fluid interface is covered with particles that are sterically jammed, the interface can exist in stable non-spherical shapes. The jammed particles thus allow the interface to behave in some ways like a solid. In this article, the authors examine the effects of small homogeneous and inhomogeneous stresses on this granular medium, or "armored bubble". They characterize the armored interface as an interfacial composite material because the interfacially trapped particles retain their individual characteristics.
