Abstract

This paper describes the results of mechanical and optical measurements on plasticized polyvinyl chloride under dynamic conditions. It covers one task (short-time characterization of the material) of a broader investigation aimed at developing experimental methods for viscoelastic stress analysis. The method of forced sinusoidal oscillations of uniaxial and simple-shear specimens was used for the determination of complex modulus and complex fringe value as functions of frequency. A procedure of correcting for wave-propagation effects was discussed. Results were obtained for frequencies up to 2800 cps in the case of the modulus and up to 1000 cps in the case of the fringe value. Both quantities were converted from functions of frequency to those of time (relaxation modulus and fringe value) by means of an approximate relation.
