The Influence of Stretch Range on the Hyperelastic Material Model Parameters for Pig’s Skin with Consideration of Specimen Taken Direction
The aim of this work was an analysis of hyperelastic material models to predict the behavior of skin tissue. The most popular Mooney-Rivlin, Humprey, Veronda-Westmann, Yeoh and Ogden models were analized. The parallel and perpendicular to the pig’s spinal directions of specimens taken were consider in the tests. The input data to the simulation were defined for parallel direction as 5, 15, 25%, for perpendicular as 10, 20, 30, 40, 50% and also as total range of engineering stretch. The results were used to prediction of mechanical behavior and comparison with experimental and literature data. The strong influence of input data range on the values of model parameters was observed.
