Can poisson's ratio be greater than 1
Web1 Answer Sorted by: 2 A Poisson ratio larger than 1/2 would correspond to a material that has its volume expand when compressed. A Poisson ratio less than -1 would … WebPoisson’s ratio (ν) can mathematically be expressed as: ν = - ε l /ε a Strain is the dimensional change of the object shape divided by the original dimension. For tensile deformation, the Poisson’s ratio remains positive. For compressive deformation, Poisson’s ratio is negative.
