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.

Have any of you done something similar to this and if yes, would you want to throw some light on the same.

 Thanking you

Prasanna
