Assessment of Mechanical and Tribological Properties of Alginate-polyacrylamide Hydrogel Matrix Composites As Minimally Invasive Cartilage Implants
(Auckland University of Technology, 2019)The advent of orthopaedic prostheses and their widespread applications have helped millions of patients worldwide to be relieved from pain and gain their mobility. However, they are still not suitable for young or middle-aged ... -
Design and Synthesis of Bilayer Nanocomposite Hydrogels for Minimally Invasive Cartilage Replacement
(Auckland University of Technology, 2021)The complex structure of healthy articular cartilage facilitates the joint withstanding the imposed pressures and retaining interstitial fluid to lessen stresses on its soft tissue, while easing the locomotion and minimizing ... -
Fatigue Crack Growth Behaviour of Cobalt-based and Nickel-based Superalloy Processed by Selective Laser Melting
(Auckland University of Technology, 2021)The production of cobalt-based and nickel-based superalloys via Selective Laser Melting (SLM) has been successfully applied in low-mass production, particularly in producing components/equipment for the spacecraft and ... -
Investigation of Tribological Performance of Ti-6Al-4V Alloy Processed by Selective Laser Melting and Electron Beam Melting Processes
(Auckland University of Technology, 2021)Powder bed fusion (PBF) additive manufacturing (AM) or 3D printing, either laser based or electron beam based, is a recent advanced manufacturing process and is being more widely applied industrially. Ti-6Al-4V alloy is a ... -
Mechanical and Tribological Characterization of Nitinol 60 Parts Manufactured by Different Powder Metallurgy Processes
(Auckland University of Technology, 2018)NiTinol 60 (60NiTi) is a Ni-rich NiTi alloy comprising approximately ~60 wt.% (55 at.%) Ni and ~40 wt.% (45 at.%) Ti. 60NiTi, when employed in a hardened state, displays outstanding properties. It exhibits excellent corrosion ... -
Mechanical Characterisation, Analysis and Modelling of Particulate Nanocomposites Printed Using Photopolymer Extrusion Technique
(Auckland University of Technology, 2019)A new photopolymer extrusion 3D printing technique is proposed in this research. This hybrid 3D printer combines the strengths of two well established and commercial 3D printers i.e. fused deposition modelling (FDM) and ... -
Numerical and Experimental Investigation of a New Load-sharing Implant for Early-onset Knee Osteoarthritis
(Auckland University of Technology, 2019)Knee osteoarthritis (OA) is one of the major causes of musculoskeletal impairment in adults. This disease is mainly characterised by progressive degeneration of the articular cartilage and, to date, there is no known cure ...
