### Abstract

There are a number of vibration applications of rubbery materials, which require the knowledge of the complex Poisson's ratio. The ratio of the imaginary part to the real part of complex Poisson's ratio is referred to as Poisson's loss factor. The magnitude of the Poisson's loss factor is investigated in this paper for homogeneous, isotropic solid viscoelastic materials with special respect to rubbers and other elastomers. The theoretical relation between the Poisson's loss factor and the modulus loss factors (shear and bulk) is derived. It is shown that the Poisson's loss factor of the nearly incompressible rubbery materials can be calculated with a good accuracy from knowledge of the shear loss factor and the dynamic Poisson's ratio. The magnitudes of the Poisson's loss factor experienced for a styrene-butadiene rubber are given and compared with theoretical predictions.
