Модель и анализ контактного взаимодействия с биотканями одномерных полимерных имплантатов

Abstract

The base stage of implantation in a kind of one-dimensional prosthetic (fixing, diagnostic) element, stretching through an aperture in a biotissue, is considered. The developed mechanical and mathematical model describes implant interaction with biotissues in the conditions of sticking and sliding of contacting surfaces. The calculated dependences for implant elongation and the maximum value of stress tensor intensity in adjoining volumes of the material are obtained, allowing one to receive a theoretical estimation of frictional and mechanical characteristics of one-dimensional implant and to determine the injuring action.
