Training, memory and universal scaling in amorphous frictional granular matter
MM Bandi and HGE Hentschel and I Procaccia and S Roy and J Zylberg, EPL, 122, 38003 (2018).
We report a joint experimental and theoretical investigation of cyclic training of amorphous frictional granular assemblies, with special attention to memory formation and retention. Measures of dissipation and compactification are introduced, culminating with a proposed scaling law for the reducing dissipation and increasing memory. This scaling law is expected to be universal, and insensitive to the details of the elastic and frictional interactions between the granules. Copyright (C) EPLA, 2018
