AN INVESTIGATION ON THE DYNAMIC PROPERTIES OF PLASTICS AND RUBBER-LIKE MATERIALS

Abstract

An improved method of analyzing the experimental data is presented, in which the characteristics of the materials tested are deduced directly through the Prony method of approximation without performing a double differentiation on the experimental results. The results of experiments performed on specimens of Geon Polyblend 503, Geon PVC, and Butyl Rubber indicated that the viscous effects were dominant. This showed that the mechanical method of representing the behavior of the material was better represented by a Voigt model than by a Boltzmann model. The stress-strain relationships had a well-marked nonlinear character. The elastic modulus and the modulus of viscosity were evidently not invariant but functions of the maximum strain.
