Material Poisson's ratio = 0.84?

[skywalker]

How does one apply a poisson's ratio of 0.84 to a linear isotropic material?

Preamble:

"...As the true behaviour of coated woven fabrics is highly nonlinear the analysis and design of Tensile Fabric Structures generally allows PVC-polyester fabrics to be modeled using Linear isotropic materials, for example:

Elastic Modulus (warp Direction) = elastic modulus (weft direction) = 600kN/m
Shear Modulus = E/20 = 30kN/m
Poisson's ratio = 0.84.

Several shell41(tension only) planar surfaces have been created, with triangular meshes, and real constants of 1mm thickness, but the problem arrises when a poisson's ratio of 0.84 is entered.

How do i over come this problem?

For homogeneous, linear, isotropic materials the Poisson's ratio is never larger than 0.5.

There are some weird materials for which the Poisson's ratio is less than 0 or larger than 0.5, but I suspect that your material is not one of those. My guess is that your experimental data is inconsistent, or the material is not isotropic.

It might have been a misprint. I bet they meant 0.48.
