Fracture mechanics of acrylic bone cement
Objective
Establishment of a novel method to characterize fracture mechanical properties of acrylic bone cement.
Motivation
- Fracture properties highly relevant for the durability of cemented endoprostheses
- Better understanding of bone cements
- Decision-making support for surgeons
Results
Developed and successfully applied the wedge splitting protocol. It was possible to investigate post-yield behaviour.
Publication in progress.
