Hyperelastic Ex Vivo Cervical Tissue Mechanical Characterization Callejas Zafra, Antonio Manuel Melchor, Juan Faris al Azzawi, Inas H Rus Carlborg, Guillermo Hyperelasticity Uniaxial tensile test Cervical tissue Nonlinearity Hyperelastic models This paper presents the results of the comparison between a proposed Fourth Order Elastic Constants (FOECs) nonlinear model defined in the sense of Landau’s theory, and the two most contrasted hyperelastic models in the literature, Mooney–Rivlin, and Ogden models. A mechanical testing protocol is developed to investigate the large-strain response of ex vivo cervical tissue samples in uniaxial tension in its two principal anatomical locations, the epithelial and connective layers. The final aim of this work is to compare the reconstructed shear modulus of the epithelial and connective layers of cervical tissue. According to the obtained results, the nonlinear parameter A from the proposed FOEC model could be an important biomarker in cervical tissue diagnosis. In addition, the calculated shear modulus depended on the anatomical location of the cervical tissue (mepithelial = 1.29 0.15 MPa, and mconnective = 3.60 0.63 MPa) . 2020-11-20T09:40:26Z 2020-11-20T09:40:26Z 2020-08-05 journal article Callejas, A., Melchor, J., Faris, I.
