MAT LAW 25 with transverse isotropy

mrtimwinkler

Hello,

i have a FRP with the following elastic parameters: E1, E2, G12, nu12.

The parameters needed in the material card are E11, E22, E33, NU12, G12, G23, G31.

 

E11 = E1

E22 = E2

E33 = E2

NU12 = nu12

G12 = G12

G23 = ?

G31 = ?

 

How do i find the missing two shear modulis?

 

Thank you very much for your help!

Kind regards

Hi @mrtimwinkler

 

There are different ways to calculate the shear modulus, for example, Semi-empirical Halpin-Tsai equation for shear modulus.

 

I would suggest you refer literature available online.
