Boundary conditions using FEM
Boundary conditions using FEM
(OP)
Im tryng to use FEM to make a model of a cell of a typical laminate composite. In this fase im comparing known results of material properties (like young modulus and so on) with the data given to me by a FEM program (ADINA) and FE models i create for each test.
Im having trouble defining the boundary conditions for some of the models.
Its easy to explain my problem using pictures...so i put them on the net:

I must excuse myself because of my bad inglish! i hope someone can help me! :)

You have correctly applied the symmetry boundary condition for the single fibre but you have forgotten the other implied symmetry planes with the adjacent fibers.
Hope this helps,

Thanks for the help people.
I was able to resolve my problem. It was about the right
boundary conditions.
A very special thanks to 'Crisb' for his help.
It was my first time at 'Eng-tips forum' and im very
pleased, im considering donating some $, i think this
forum deserv it! :)

You say "A very special thanks to 'Crisb' for his help" then you should at least award him a star for his help to you !
