Mathematical Models of Sand
Friday, October 12, 2007 4:00 p.m. in ETC 4.120 Professor Charles Radin Department of Mathematics The University of Texas at Austin http://www.ma.utexas.edu/dev/math/index.html Sand exhibits some unusual mechanical properties, for instance: dilatancy, the Janssen effect and random close packing. Attempts to develop a theory to explain such behavior usually begin with analyses of dense packings of…
