Abstract

To describe the mechanical behavior occurring in biological materials during the load, the hyperelastic material models are often used. The purpose of this work was to analyze the influence of three different strain rates on the results of fitting the characteristic curves of selected multi-parametric hyperelastic material models (neo-Hookean, Mooney-Rivlin, Humprey, Yeoh, Veronda-Westmann and Ogden). Experimental data were obtained from uniaxial tensile tests of pig skin tissue. Three values of speed were set at 1, 5, 10 mm/min. Correlation coefficients and fitting error were evaluated. The study revealed the relationship between the level of load speed and the values of model parameters.
