Experimental Investigation of Plasticized Polyvinylchloride using the Split Hopkinson Pressure Bar Technique 2000-01-0610

Characterization of materials used in the automotive industry is often done via component testing. A strict regimen of tests is conducted on a component to determine material parameters for numerical simulations of more complicated loading conditions. Separation of material constants and geometrically- or experimentallyinduced effects is difficult with this method of characterization. Well-controlled experiments that determine the material response in basic deformations allow material properties to be determined. In this paper low strain rate and high strain rate experimental responses of dummy skin material (i.e. plasticized polyvinyl chloride) are presented. Details of the experimental procedures used to acquire the data are also included. In addition, a rate-dependent constitutive model for the plasticized material is developed, and its simulated results are compared with low strain rate results.
