For MSC/NASTRAN 2000, you input the material properties with the Young Modulus E , G and the POISSON ration . You input only one number for E and the others because NASTRAN considers the material as isotropic.
But how can you enter the properties for composites materials ?
In this case , Young Modulus and the others are matrix (Exx , Exy etc ...)
