RHEOLOGY, MICROSCOPIC DYNAMICS AND MATERIAL FAILURE IN THE CREEP OF A COLLOIDAL GEL

摘要

The mechanical properties of amorphous solids such as glasses or gels are currently a topic of intense research, with implications in material science as well in fundamental condensed matter physics. Traditionally, researchers have investigated the relationship between two macroscopic quantities: the stress applied to the sample and the resulting strain. Recent works aim at gaining a deeper understanding of the origin of the Theological properties, by coupling rheology to structural and dynamical measurements.
