In situ neutron diffraction mapping of tri-axial stress distributions in particulate systems. Compacting powders, which are critical in industries such as metal, advanced ceramic and pharmiceutical manufacturing, will be studied in real time using advanced neutron diffraction techniques. This will allow the three-dimensional mapping of stresses and strains within small volumes of the powder deep inside realistic compaction equipment.

This project aims to develop a novel hierarchical multi-scale modelling framework to understand factors that influence the mechanical deformation behaviour of the extracellular matrix (ECM) such as cartilage, whose mechanical performance is critical to human wellbeing. Modelling ECM presents significant challenges due to the need to incorporate effects at scales from atomic interactions up to the fibre network in a continuum model. The proposed framework follows ECM's natural hierarchical structure and integrates efficient models for each key structural scale based on rigorous experimental validations. It is expected to provide a powerful tool for designing successful artificial ECM materials and understanding the mechanisms of the ECM degradation.Read moreRead less
Multiscale Study on Biomechanical Roles of Soft Tissue on Bone Remodelling. The project aims to increase our knowledge of the processes of bone remodelling and the role of soft tissue in this process. Mechanical force is a key stimulus for regulating bone remodelling. A significant question in biomechanics is why orthodontics only use very small forces (1 Newton) to generate significant oral bone remodelling, whereas prosthodontics that apply three orders of magnitude higher forces (~1000 Newton ....Multiscale Study on Biomechanical Roles of Soft Tissue on Bone Remodelling.

A significant question in biomechanics is why orthodontics only use very small forces (1 Newton) to generate significant oral bone remodelling, whereas prosthodontics that apply three orders of magnitude higher forces (~1000 Newton) do not move dental implants. This project aims to develop new multiscale modelling and remodelling techniques in computational mechanics to explore the roles played by connective soft tissue in bone adaptation. Expected project outcomes would increase our understanding in biomechanics and affect health care disciplines such as orthodontics, prosthodontics and orthopaedics.Read moreRead less
Novel quantitative sizing of inaccessible and hard-to-inspect defects to address the challenges posed by innovations in airframe design. Modern unitised aircraft structures cannot be reliably inspected using traditional techniques. This project will develop new techniques to quantify defects required for this innovation in aircraft component design. This research will improve the through-life support of future metallic and composite aircraft structures and improve air safety.

Summary
Multiscale design of hierarchical structures for crashworthiness. This project intends to develop new hierarchical materials and structures for light weight and crashworthiness by mimicking impact-bearing biological materials. Environmental and road safety concerns mean that vehicles must try to compromise between light weight, to reduce fuel consumption, and crashworthiness. To some extent, design optimisation of conventional materials and structures has reached its limits. This project aims to ....Multiscale design of hierarchical structures for crashworthiness. This project intends to develop new hierarchical materials and structures for light weight and crashworthiness by mimicking impact-bearing biological materials. Environmental and road safety concerns mean that vehicles must try to compromise between light weight, to reduce fuel consumption, and crashworthiness. To some extent, design optimisation of conventional materials and structures has reached its limits. This project aims to develop new biomimetic multiscale design methods to generate novel hierarchical structures for automotive applications. The study is expected to provide the automotive industry with novel approaches and designs to improve both the weight and crashworthiness of vehicles.Read moreRead less

Intravascular stents are a class of lifelong micro-devices to support blood vessel for restoring circulation. Despite its remarkable initial outcome, the high rate of long-term mechanical failure remains a major concern. This project will tackle plasticity, fatigue damage and fracture across different length scales. The proposed optimisation is expected to minimise failure, thereby enhancing the longevity and reliability of stent therapy. This will have significant benefits, such as accommodating variations in stents and service conditions for achieving a long-lasting and reliable therapeutical outcome.Read moreRead less
