Coexistence of Liquid and Solid Phases in Flowing Soft-Glassy Materials

Magnetic-resonance-imaging rheometrical experiments show that concentrated suspensions or emulsions cannot flow steadily at a uniform rate smaller than a critical value ( ${\stackrel{\ifmmode \dot{}\else \.{}\fi{}}{\ensuremath{\gamma}}}_{c}$). As a result, a ``liquid'' region (sheared rapidly, i.e.,... View More
