B05 - Assessment of the mechanical reliability of porous and functionally graded implant structures by local damage approach

Summary of the work programme

The goal of the project is the assessment of the mechanical reliability of electrically active implants with respect to the limit load behaviour and the fatigue strength. Based on experimental, analytical and numerical investigations, the local damage and failure mechanisms of porous and functionally graded basic structures, which are additively manufactured, will be identified under different loading conditions. From this, mechanism-based concepts for a substantiated prediction of the structural behaviour will be derived and the topology of the structures mechanically optimised.
