Hi Every Body
I am trying to simulate compression test for an aluminum foam.
At first,I modeled a unit cell to create my final shape by repeating method(copy cell side to side).
Then I merged these cells to reach a unified shape.
As compression test is a quasi-static process,I try to run it by a dynamic explicit in Abaqus.
But it takes too much time so that each step time is less than 10^-5 for simple model and explicit analysis may take 4-5 days
by the way meshing of this foam is really hard cause I have to mesh complete model after merging unit cells( instead of mesh a single cell)
implicit dynamic take long time too.
best regard for your intelligently ideas

foam modeling
i have presented a new method for the first time to model of metal foams that subtracts stochastic cells from a desired volume
I simulate a metal foam
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) ?
