Two-state shear diagrams for complex fluids in shear flow [PDF]
, 1999 The possible "phase diagrams'' for shear-induced phase transitions between two phases are collected. We consider shear-thickening and shear-thinning fluids, under conditions of both common strain rate and common stress in the two phases, and present the ...
