With the ageing population, there is increasing demand for synthetic materials that can regenerate bone. However, purely synthetic bone-substitute biomaterials cannot regenerate large bone defects in weight-bearing conditions due to their fragility. This project aims to develop a customisable, biodegradable, biocompatible and mechanically strong and tough scaffold that overcomes this long-standing problem. The project aims to achieve this by applying an innovative combination of cutting-edge 3D printing technology, advanced computational modelling and design techniques to produce a next-generation bioceramic scaffold with optimised architecture. This approach aims also to enable the possibility of producing custom-made implants for individual requirements.Read moreRead less

This project aims to develop a novel approach for early damage detection. It relies on a systematic experimental investigation of nonlinear ultrasonic interaction between different input wave modes in the presence of damage, so as to identify optimal mode selections and operating parameters that will maximise the sensitivity to particular forms of structural damage. The effects of in-service loading on wave-mixing response, and non-contact detection suitable for hard-to-inspect surface conditions, will also be investigated. The new developments will help transform existing schedule-based maintenance practice to a condition-based maintenance paradigm, to achieve significant cost savings in maintenance.Read moreRead less
