Modelling the simple shear behaviour of clay considering principal stress rotation

“…A remedying approach is to use t r t r ijkl kl ijkl kl N l N l as the deviatoric flow direction, where || || denote the norm and t ijkl N is the deviatoric tangential projection tensor [18]. A recent study [19] showed that in the simple shear, these two deviatoric flow rules produce almost identical results. Therefore, the simpler choice of Eqn ( 11) is kept.…”
