did you use anysotropic material ?, in abaqus, for elastic properties, if you use engineering constant instead of anisotropic, you only need to fill the modulus and poissons ratio for all directions. Typically, if you use a UD, transverse shear will be near to in plane shear in 13 direction and to matrix shear properties in 23, in the case of woven fabric, you might refere to similar material from the literature. If you can give me some more details, maybe I can help more.

I want to design and analyze composite mono leaf spring for a light vehicle (static load of 0.3 ton). Leaf springs are usually assumed as beams during analysis. E-Glass/Epoxy is selected for its suitability where the E-Glass is unidirectional due to its benefit for such loading. A preliminary design based on static load results about 45 mm thick laminated beam. This may require stacking of over hundred lamina. Modeling both the composite layup and analysis using Abaqus as a continuum solid element is required where I stuck as to how to do. I thought that unidirectional composite lamina is generally considered as orthotropic material under plane stress condition. Modeling as anisotropic material might be extremely difficult since materials have properties that vary with the direction in which they are measured. Your help in this is gratefully acknowledged.

Thank you.

I have a paper which contains E-Glass/Epoxy lamina and fiber properties .I hope that it will be useful for your analysis.
