I simulate a metal foam microstructure in abaqus but now in material property I dont know which kind of material can I use?
For example I used elasticity and plastic(crushable foam) or elasticity and plastic(isotropic hardening) ?
Journal of Applied Mechanics (JAM) received 526 submitted manuscripts in 2013. Among them 4 are still in review.
The average time for the 1st round of review, with the decision to accept, or reject, or revise, is 18 days. After the 1st round of review, the average time to make the final decision is 34 days, which include both the authors' revision time and 2nd (and more) round(s) of review.
After acceptane the uneditted manuscript appears online with the assigned DOI within 48 hours.

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.

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.
