| contents | Comparative study of stress relaxation phenomenological constitutive modeling of carbon black-reinforced natural rubber-based compounds Manuel Alberto Guzmán-Sánchez Ingeniería viscoelastic natural rubber Stress relaxation constitutive modeling Viscoelastic properties of rubber materials are due to the combination of the dual response as an elastic solid and a viscous fluid. This behavior yields in time-dependent mechanical properties; thus, phenomena such as stress relaxation, creep, energy dissipation, hysteresis, and strain rate are observed. In this study, three different carbon black-reinforced natural rubber compounds were experimentally evaluated under stress relaxation and several linear phenomenological constitutive models were fitted to evaluate their viscoelastic parameters. It was observed that both the elastic and viscous parameters increase in a non-linear relation as the strain and carbon black content increase, and the viscous parameters were dependent on the configuration of the model. Maxwell and Zener models exhibited fitting values of 76.08 and 95.10%, respectively, while the Wiechert model showed the best fitting values (above 98.40%) and can be adequately used to estimate the relaxation process of carbon black-reinforced natural rubber applications. 2021 artículo científico 0012-7353 https://www.redalyc.org/articulo.oa?id=49668215007 https://www.redalyc.org/journal/496/49668215007/ https://www.redalyc.org/journal/496/49668215007/html/ https://www.redalyc.org/journal/496/49668215007/49668215007.epub https://www.redalyc.org/journal/496/49668215007/movil 10.15446/dyna.v88n216.89446 en http://www.redalyc.org/revista.oa?id=496 Dyna application/pdf Universidad Nacional de Colombia Dyna (Colombia) Num.216 Vol.88 |
