Fatigue of hip prostheses - influence of material and manufacturing process

Objectives:

This study aims firstly to develop a tool for the fatigue design of hip prosthesis, taking into account the influence of the range of manufacture (forging, surface treatment, heat treatment) on the state of material. Second, we seek to determine quickly the fatigue properties of artificial hip joints by testing self-heating.

Originality:

rapid characterization in fatigue tests of self-heating,
taking into account non-standard state of the material caused by manufacturing,
establishment of a support tool in fatigue design of hip prostheses.

Industrial partner:

Stryker Benoist-Girard

State non-standard, self-heating test structure (hip), probabilistic model for two scales
