In this work, we present, for the first time, the results of the measurement of force chains in 3D granular materials that are not photoelastic. The technique relies in the recently proposed Granular Element Method (GEM), which enables the measurement of inter-particle forces or force chains in general opaque three-dimensional granular materials. These results represent a significant advancement to photoelasticity, which until now has been the sole method for measurement of forces in particle assemblies. We present an example using rubber particles and DIC to show the promise of the method.
