Densification using COMSOL

Hello!
I need help in changing the non-linear solid mechanics equation using the user-defined section. I checked other models in the non-linear node (e.g. Ramberg-Osgood, Power law, uni-axial data), but I found them not applicable.
σ=G(ε ̇ )+K tr((ε ̇ ))-1/3 G tr((ε ̇ ))i+Pli
where (ε ̇ ) is the strain rate tensor, i is the identity tensor, Pl is the sintering stress, ψ and φ are the bulk and shear moduli, respectively.
Any help is much appreciated.
Regards, Faris
