GRP mechanical properties

Hi,
can you tell me what should I put in the material style for GRP because I can find much more info on some sites and I am not sure what strength should I use.

(in the actual datasheet for the grp I uset here are tensile strength (long and transverse as well), Tensile modulus (l and t)m compressive Strength (l & t), Compressive Modulus (s & t), shear strength (l&t), flexular strength (l&t) and flexular modulus (l&t) and Poissons Ratio (l & t).
So I am a bit confused....

many thanks,
Richard K.

Glass Reinforced Plastics, like all Fibre Reinforced Plastics, are
anisotropic materials. That's the fancy word for them having properties
that usually differ significantly along each of the primary axes.

Other than using the specific gravity (density) to calculate the mass,
Inventor doesn't use the mechanical properties, so you can fill in whatever
you want.

From what I can see, and I hope someone proves me wrong, the FEA which comes
with IV Simulation and, I presume, Pro -only deals with isotropic
(properties are considered to be equal in all directions) materials. It has
no place to accept properties that differ from one principal axis to
another.

Inventor has GFRP (Glass Fibre Reinforced Plastic) which may be of some use to you, I'm not well up on the physics of the materials so don't know how similar it is to GRP.

do you realize the question was asked 2.5 years ago?  (I'm guessing Richard is no longer expecting/waiting for an answer here...)
