I’m trying to make a comparation between prediction methods (like the Rule Of Mixtures, Halpin-Tsai and FEM) and real tests made in unidirectional fiber reinforced composites.
For this purpose i need the properties of the fiber and matrix (Young modulus, poison) and the composite test...
Im sorry, im new here 'Johnhors'. But i already corrected my mistake. A full star for 'Crisb', is tip was very helpfull. But i must thank again everyone that posted and tryed to help...i hope one day i can help all of you in return! :)
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! :)
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...
