Why the VVF of GTN model within Abaqus keeps 0
I calculated an example of unaxial tension using GTN model offered by Abaqus. I followed all the instructions found in CAE User's and Analysis User's manual in Abaqus documentation. No error or warning was issued but the result seemed ridiculous, since VVF, VVFG and VVFN keeped 0 throughout the process while equivalent plastic strain keeped increasing(which showed the material had come into plastic deformation). I don't know what went wrong, looking forward to you reply.

An elastic phase field model for thermal oxidation of metals: Application to zirconia
http://www.sciencedirect.com/science/article/pii/S0927025614002031
Abstacrt: A multi-phase field model was developed for non-selective oxidation of metals which captures both the oxidation kinetics and stress generation. Phase field formulation involved a non-conserved phase field variable as the marker for the metallic substrate, oxide scale, and a fluid phase containing oxygen, and a conserved phase field variable representing the concentration of oxygen.

presenting a new method to model of metal foams
i have presented a new method for the first time to model of metal foams that subtracts stochastic cells from a desired volume and changes it to a foam.
i would like to know if there is any phd position for this?
thank u for your consideration :)
