orthotropic material simulation

Hi, please help me on the simulation on the orthotropic material in ABAQUS. I have the parameters for the material density=1584;

Ex=127.9e9

Ey=10.27e9

muxy=0.22;

muyx=0.0177;

Gxy=7.312e9;How can i use the orthotropic or engineering constant to simulate the material. I want to calculate frequency for orthotropic plates.



Graphite epoxy plates



Graphite/epoxy consisting of 12 plies oriented at 0 and fabricated from Fiberite

Thank you for your concern.
