Impact properties of an end of life tires' rubber. Numerical validation considering large strain and strain rate conditions

In a previous work, the experimental viscoelastic properties of a renewed rubber obtained from the recycling of end-of-life tires (ELTs) were presented, [1]. The material was tested in the laboratory by means of impact tests that revealed how the behavior of the rubber depends on the strain rate in such a case. Due to the loading conditions of high strains and high strain rates, the nonlinear viscoelastic Bergtröm-Boyce (BB) model, defined by nine parameters, was selected to fit the behavior of the material.
