Computer models of biomaterials used for manufacture of flap apparatus of prosthetic heart valves

Abstract

The physical-mechanical characteristics of materials-components of bioprostheses of heart valves presented in clinical practice in Russia, with subsequent adaptation of properties for numerical modeling tasks, have been obtained and generalized. It is shown that all the studied materials have a pronounced nonlinearity and can be represented only in the form of polynomial models. Comparison of the results of computer modeling based on the obtained coefficients of materials showed no differences with the data of full-scale bench tests, which made possible to verify computer models.
