Biomaterials: Joints and problems of contact interfaces

Abstract

Intensive development of modern materials enables their increasing application in biomedical engineering. To make the material under consideration applicable, it should be made biocompatible with organic material. One of the problems encountered in design of the implant joints in a human body is the problem of the interfaces in contact, caused by significant difference in mechanical properties of the materials applied. Good understanding of these problems is of immense significance in prevention of premature failures of the structures in biomedical engineering.

Intenzivan razvoj savremenih materijala omogućava njihovu sve širu primenu u biomedicinskom inženjerstvu. Da bi razmatrani materijal mogao da se primeni kao bimaterijal, potrebno je da se obezbedi biokompatibilnost sa organskim materijalom. Jedan od problema koji se javlja pri projektovanju spojeva implanta u ljudskom organizmu je problem dodirnih površina izazvan velikom razlikom u mehaničkim osobinama materijala koji čine spoj. Stoga je dobro razumevanje ove problematike od izuzetnog značaja u sprečavanju prevremenih otkaza konstrukcija u biomedicinskom inženjerstvu.
