One of our academic collaborators, Prof Karen Daniels from North Carolina State University, recently gave a brilliant presentation of her work. The topic was on ‘The Role of Force Networks in Granular Materials’ and a teaser of our collaborative study is shown at approximately the 15 min timeframe…
Abstract:
Granular materials are inherently heterogeneous, and continuum models of properties such as rigidity and sound speed often fail to quantitatively capture their dynamics. One likely reason for these difficulties is that internal stresses are transmitted via a chain-like network of strong forces, introducing a secondary, meso-scale structure to the system. In my talk, I will describe several experiments on two-dimensional photoelastic granular materials which bridge particle-scale, meso-scale, and continuum-scale approaches. These experiments allow us to both investigate the statistical ensembles from which force networks are drawn, as well as probe their effects on mechanical properties such as sound transmission, rigidity, and rheology.
