Composite analysis
Composite analysis
(OP)
Hello,
I have a composite material (Matrix and random glass fibers) unit cell(3D), I want to get the stress vs strain curve of the composite material. For that I have inserted the elastic and plastic properties(true stress and true plastic strain)of matrix, and elastic properties of fibers since fibers are brittle. I have applied the load in steps in order to get a converged graph. The results are not matching even in the elastic region. How do I proceed? I have several questions.
1. I am not sure about the applied load, what load should be applied?
2. For this non linear solution, the static general analysis is sufficient?
Thanks in advance

RE: Composite analysis
1) I would recommend creating a coupling constraint between a master node and all the nodes along the face of the unit cell and apply a concentrated force to the master node.
2) Yes
If your results are not matching, you may want to adjust fiber/matrix properties.
