-The problems connected with the singular point of the bi-linear model are here avoided. Since the shear strain rate <math display="inline">\tilde{\mu }=\mu +{\tau }_0\mbox{\;  }m</math> as <math display="inline">\dot{\gamma }\rightarrow 0</math>.

 In order to introduce the constitutive model for 3D problems, the following ''equivalent strain rate  ''<math display="inline">\dot{\gamma }</math> and ''yield stress τ''<sub>0</sub> are defined as the second invariants of the rate of strain tensor ('''''ɛ''''') and of the deviatoric part of the stress tensor ('''''τ'''''), respectively
