Validation of a finite element model of the human abdominal fascia
Journal of Mechanics in Medicine and Biology(2022)
Abstract
Finite element (FE) analysis is widely used for exploring the mechanical properties of layers and organs of the human body. The aim of this study was to construct and validate an FE model to monitor human abdominal fascia behavior under an uniaxial tensile test. In this study, our previous experimental results for abdominal fascia from three human cadavers where the age distance is about 20 years are chosen to validate FE model. The Yeoh hyperelastic constitutive model was used for the chosen abdominal fascia samples. The FE analysis was applied to simulate the experimental conditions and to calculate stress and strain distributions generated by the uniaxial tension test. The fitting accuracy of the experimental data to the theoretical one was evaluated. The analysis of the results showed a good correlation between the numerical and experimental data. The percentage error between experimental and FE results is in the interval 4.7–9.4%.
