any idea about boundary conditions to be used when modelling a unit cell of a foam
Dear friends / distinguished imechanicians,
I am trying to use micromechanics in foams to numerically compute the elastic constants using one unit cell. I see some literature available when simple unit cell shapes are assumed (like cubical or hexagonal). However there is nothing specific about modelling for tetrakaidecahedral foams. Assuming the right boundary conditions would be critical for computing the constants. I am not able to come up with a reapeating pattern for determining the places to apply the boundary conditions.
