Резюме: Objective: Based on literature data, the parameters of the hyperelastic properties of the vaginal wall of a female rabbit in transverse and longitudinal directions are calculated. Materials and methods: Calculations were carried out based on uniaxial tensile tests of autopsy material in the strain range 0-2.04 using the computer algebra system Mathcad 15.0. The most common hyperelastic models in continuum mechanics are considered: neohookean, Mooney-Rivlin, Ogden, Yeoh, polynomial and Veronda-Westmann. Results and discussion: To describe the mechanical behavior of the vaginal walls, the hyperelastic polynomial model and the Yeoh model are best suited; the neohookean model is least suitable. The latter, in addition, exhibits mechanical instability at small deformations, which is unusual for biological tissues. Linear, bilinear and exponential models of the vaginal wall were also considered and numerical values of the model indicators were obtained. The best performance among these models was demonstrated by the deformation exponential model. Conclusion: The relevance of the research is due to the need to know the parameters of the deformation properties of the vaginal walls when developing replacement materials for prostheses and functional analogues in surgery of the female pelvic organs.
