For the isotropic energy part, we select the amended non-Gaussian strain energy density model, while the energy fiber effects are added by considering the equivalent anisotropic volumetric fraction contribution, as well as the isotropized representation form of the eight-chain energy model that accounts for the material anisotropic effects. Furthermore, our proposed material model uses a phenomenological non-monotonous softening function that predicts stress softening effects and has an energy term, derived from the pseudo-elasticity theory, that accounts for residual strain deformations. The model’s theoretical predictions are compared with experimental data collected from human vaginal tissues, mice skin, poly(glycolide-co-caprolactone) (PGC25 3-0) and polypropylene suture materials and tracheal and brain human tissues. In all cases examined here, our equivalent material model closely follows stress-softening and residual strain effects exhibited by experimental data" , "dc.format.mimetype": "application/pdf" , "dc.language.iso": "eng" , "dc.publisher": "MDPI (Multidisciplinary Digital Publishing Institute)" , "dc.relation.isformatof": "Reproducció digital del document publicat a: http://dx.doi.org/10.3390/ma7010441" , "dc.relation.ispartof": "Materials, 2014, vol. 7, núm.1, p. 441-456" , "dc.relation.ispartofseries": "Articles publicats (D-EMCI)" , "dc.rights": "Attribution 3.0 Spain" , "dc.rights.uri": "http://creativecommons.org/licenses/by/3.0/es/" , "dc.subject": "Materials biomèdics -- Biocompatibilitat" , "dc.subject": "Biomedical materials -- Biocompatibility" , "dc.title": "On the Rule of Mixtures for Predicting Stress-Softening and Residual Strain Effects in Biological Tissues and Biocompatible Materials" , "dc.type": "info:eu-repo/semantics/article" , "dc.rights.accessRights": "info:eu-repo/semantics/openAccess" , "dc.embargo.terms": "Cap" , "dc.relation.projectID": "info:eu-repo/grantAgreement/EC/FP7/247476" , "dc.type.version": "info:eu-repo/semantics/publishedVersion" , "dc.identifier.doi": "http://dx.doi.org/10.3390/ma7010441" }
