Laminate Poisson's Ratio > 0.5
Laminate Poisson's Ratio > 0.5
(OP)
I am using CLT to calculate the modulus for a whole stack up. I got a poisson's ratio 0.7 for 4 plies of +/-45 deg.
When I use this data in FEM with orthotropic material, there is an error if the possion's ratio more than 0.6. May I know why?
Would higher poisson's ratio result in higher transverse strain to cause large interlaminar stress?

I figure out the issue. It might be a bug but then I work with the unit and no more issue now.
