Overview

The treatment of rotator cuff (shoulder) repair is sub-optimal with up to 50% failure rate in the first year. This situation is very alarming. One cause of implant failure is its poor mechanical strength as the rotator cuff is loaded under static as well as dynamic conditions.

Fatigue testing of scaffold structures is costly and time consuming process. Other factors such as relative density, cell topology, and struts' geometry also effect the fatigue behaviours of materials. Hence, the study of these factor before manufacturing is important.

Research activities

In this project, you will:

  • Study appropriate numerical and computational models for in-vitro mechanical simulation of PCL scaffolds produced by melt electro writing (MEW) technique for rotator cuff repair
  • Analyse simulated data
  • Perform some experimental validation

Outcomes

We expect the results of this topic to include:

  • gain new insights into mechanical behaviour of scaffolds of certain geometries
  • reduce experimentation cost and time
  • publish results in journals

Skills and experience

Good knowledge in CAD/CAE, mathematical modelling, manufacturing and materials engineering is desirable.
