Stressed Soft Matter : Yielding, hardening and softening soft solids

Emanuela Del Gado Department of Physics, Georgetown University

Time-dependent and process-dependent properties of soft jammed solids like gelled networks, compressed emulsions or colloidal glasses, stem from stress heterogeneities frozen-in during solidification and their coupling with an imposed deformation. I’ll discuss recent novel insights gained through numerical simulations of statistical microscopic models that suggest how to control the persistence of flow inhomogeneities upon yielding, and provide new cues to design softening, hardening and brittleness in soft solids.
