These changes can quantitatively be assessed if a suitable set of biomaterial constitutive parameters could be fitted onto the in vitro response from pressure myography. In Simon et al (1970), a pressure-diameter dataset reflecting the internal pressurization stage was provided. However, this data did not include the excised state. We developed an analytical continuum-based computational procedure to pull the current state back to the excised (reference) state. Using this procedure the data was fitted to a simple exponential model, and a 56% decrease in the shear modulus and a 19% decrease in the exponential constant were observed. Similar observations were made for the hyperelastic fibre-reinforced continuum model by Holzapfel et al (2000). In conclusion, the parameter identification process may be hindered as a result of an incomplete or partial dataset. Inverse deformation mapping may be used to<br>\nproduce the missing data.</p>", "headline": "Identification of passive constitutive arterial tissue parameters from pressure myography based on inverse hyperelasticity", "identifier": 263268, "image": "https://aperta.ulakbim.gov.tr/static/img/logo/aperta_logo_with_icon.svg", "inLanguage": { "@type": "Language", "alternateName": "eng", "name": "English" }, "keywords": [ "soft-tissue biomechanics", "parameter identification", "inverse deformation", "vasculatory system", "hyperelasticity", "finite element analysis" ], "license": "https://creativecommons.org/licenses/by-nc/4.0/", "name": "Identification of passive constitutive arterial tissue parameters from pressure myography based on inverse hyperelasticity", "sameAs": [ "https://doi.org/10.2139/ssrn.4607650" ], "url": "https://aperta.ulakbim.gov.tr/record/263268", "version": "0.8" }
