problem in modeling an FRP composite
(OP)
To model an FRP composite with fibers in one direction , in material properties and section definition , if the data are as bellow , how should I define this material ?
Material parameters
Characteristic stiffness values and transverse contraction
Elasticity modulus GPa E0° 17/23/28*
Elasticity modulus GPa E90° 8,5
Shear modulus MPa G 3,00
Poisson's ratio - V0°,90° 0,23
Poisson's ratio - V90°,V0° 0,09
also I am not sure that how many layers are there in this composite , due to the difference btw the E1 and E2.
using Engineering Constants requires E in 3 directions and also v , but the data are as mentioned

otherwise set your section as solid, and material type elastic isotropic rather than engineering constant

I would define the material using Engineering Constants (all the values can be determined or estimated using the information in the above blog posts and your data). If you don't know the number of layers, do you at least know the percentages of various orientations (ex. 50/40/10 meaning 50% 0s, 40% 45s and 10% 90s)?
