Investigation of the influence of endoprostheses material properties upon the distribution of the pressure and the wear in the contact surface

Abstract

The problem of impact durability is discussed. The model of rods is used for the analysis of endoprosthese acetabular and ball contact. Experimental works evaluating different biological lubricant influence on the wear of the implant were done. Randomised blocks mathematical model of dispersed analysis is worked out and calculations using experimental data are done. Results of experimental, statistical and analytical work are presented.
