Poisson ratio of an elasticity tensor
Description
\[\nu = \frac{-S_{ijkl} x_i x_j y_k y_l}{S_{mnop} x_m x_n x_o x_p}\]
Syntax
nu = PoissonRatio(S,x,y)
nu = PoissonRatio(S) % isotropic caseInput
| S | elastic complianceTensor |
| x | vector3d tension direction |
| y | vector3d perpendicular direction |
Output
| nu | Poisson ratio |
