Résumé
This paper presents an evaluation of the elastic properties of porcine vocal folds through uniaxial tensile tests. Inferior vocal fold tissue samples were subjected to tension in the longitudinal direction while digital image correlation techniques were employed to determine strain values throughout the tests. The stress-strain results showed a low-strain linear region, followed by both a nonlinear exponential and then a higher strain linear region. Data from 16 porcine vocal fold samples were analyzed following a similar optimization method as proposed in prior studies [1] to yield continuous model parameters which describe the elastic properties of the tissue. The average low and high strain linear modulus values were found to be 17.86 kPa and 609.27 kPa, respectively. The model also identified the location of two transition points: p
