We will illustrate extended structures, bridges and arches, that are formed in computer generated, non-sequentially stabilized, hard sphere deposits. The bridges have well defined distributions of sizes and shapes which reflect the constraints associated with the packing and the details of the deposition process. Bridges are fundamental micro-structural elements of real granular materials and in many situations they are influential in the development of heterogeneous mechanical properties and flow instabilities.
This is a weekly series of informal talks given primarily by members of the soft condensed matter and statistical mechanics groups, but is also open to members of other groups and external visitors. The aim of the series is to promote discussion and learning of various topics at a level suitable to the broad background of the group. Everyone is welcome to attend..
