(OP)
Hello,

I want to do some linear analysis in Nastran using MAT8. I have E1, E2, nu12 and nu21 values from the material datasheet. According to the Quick Reference Guide, if needed, I can assume that G1Z = G2Z = G12 but I don't have G12 value. I know that G12 is uncoupled from the rest of the parameters but, is there any way to estimate its value?

Thanks in advance.
