(orcid)0000-0001-8900-0039 A New Multiparameter Model for Multiaxial Fatigue Life Prediction of Rubber Materials 2020 Access copy available to the general public Unrestricted Most of the mechanical components manufactured in rubber materials experience fluctuating loads, which cause material fatigue, significantly reducing their life. Different models have been used to approach this problem. However, most of them just provide life prediction only valid for each of the specific studied material and type of specimen used for the experimental testing. This work focuses on the development of a new generalized model of multiaxial fatigue for rubber materials, introducing a multiparameter variable to improve fatigue life prediction by considering simultaneously relevant information concerning stresses, strains, and strain energies. The model is verified through its correlation with several published fatigue tests for different rubber materials. The proposed model has been compared with more than 20 different parameters used in the specialized literature, calculating the value of the R-2 coefficient by comparing the predicted values of every model, with the experimental ones. The obtained results show a significant improvement in the fatigue life prediction. The proposed model does not aim to be a universal and definitive approach for elastomer fatigue, but it provides a reliable general tool that can be used for processing data obtained from experimental tests carried out under different conditions. info:eu-repo/grantAgreement/ES/DGA/T08-20R info:eu-repo/grantAgreement/ES/DGA/T48-20R info:eu-repo/semantics/openAccess by http://creativecommons.org/licenses/by/3.0/es/ 4.329 2020 POLYMER SCIENCE 18 / 87 = 0.207 2020 Q1 T1 0.77 2020 Polymers and Plastics 2020 Q1 Chemistry (miscellaneous) 2020 Q1 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Elduque, D.
