Property modellingTensile behavior of post-consumer recycled high-density polyethylene at different strain rates

This paper describes a study of the tensile behavior of post-consumer recycled high-density polyethylene (HDPE) tested at different strain rates. The main goals of this study are to experimentally characterize recycled HDPE and to propose a one-dimensional viscoelastic phenomenological model able to yield a physically realistic description of strain rate sensitivity and damage observed in tensile tests that can be used in engineering problems. The material parameters that appear in the model can be easily identified from just three tests performed at different constant strain rates. The results of tensile tests conducted at different prescribed strain rates are presented and compared to model estimates of damage progression, and show good agreement.
