Densification using COMSOL

Please login with a confirmed email address before reporting spam

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
