Abstract: |
Various accurate and approximate formulations for static viscoelastic poisson’s ratio and dynamic complex poisson’s ratio are discussed. Formulation of viscoelastic poisson’s ratio for a composite solid propellant is given based on experiments and computations. This paper is available to obtain,accurate viscoelastic poisson’s ratio of solid propellant. |
