Резюме: Objective. Unfortunately, knowledge about the mechanical properties of breast tissue is limited, although it has been proven that the stiffness of biological tissues can serve as a predictor of cancer. Despite the successes in the theoretical consideration of aspects of hyperelasticity and a wide range of formulated models, there are very few original works devoted to the practical definition of parameters of hyperelastic models, interpretation and discussion of their values. In addition to the potential for use in cancer diagnosis and classification, the data presented in this topic is quite important for applications such as surgery planning and virtual reality-based physician training systems, where accurate nonlinear modelling of tissue response is required. Goal: This report compares the literature data on the numerical values of the parameters for the most common hyperelastic models each other and with the new results of our own calculations. Materials and methods: Calculation of the material constants of hyperelastic models in our own research was performed in Mathcad 15.0 using the genfit and corr functions. Results: Numerical values of the parameters of the neohookean, Mooney-Rivlin, Ogden, polynomial, Yeoh, and Veronda-Westmann hyperelastic models of breast tissue were obtained. Conclusion: The results of calculating the parameters of the hyperelastic models of the mammary gland vary significantly, requiring further research.
