| Abstract: | An example of an orthorhombic material is constructed such that even though the strain-energy density is positive definite, Poisson's ratio may take an arbitrarily large positive value for one pair of orthogonal directions and take an arbitrarily small negative value for another pair of orthogonal directions. |
