Fusion Bonding and Consolidation of 3D Printed Continuous Carbon Fibre Reinforced Polyamide Composites

Abstract:

Extremely large amplitude of resonant wave oscillation is often encountered in the narrow gap between two floating bodies. Nonlinear behavior of the resonant response is numerically investigated based on a fully nonlinear potential flow model in time domain, rather than the linear one in frequency domain. Nonlinear harden spring behavior of the piston-mode wave oscillation in gap is found and confirmed to be resulted from the second order effect with a rise of the mean water level in the narrow gap. The nonlinear solutions demonstrate multiple response components. Their roles in the dynamic response are clarified. Super-harmonic resonance is identified with the nonlinear model, including the second order and third order resonance, and the combined harmonic resonance.

Lin Ye currently is a full professor at the School of Aerospace, Mechanical and Mechatronic Engineering (AMME) and the Director of the Centre for Advanced Materials Technology (CAMT) of The University of Sydney. He received his BEng degree from Harbin Engineering University in 1982, and MEng in 1984 and PhD in 1987 from Beihang University (formerly Beijing Institute of Aeronautics and Astronautics). Then, in early 1988, he was appointed Lecturer at Xi'an Jiaotong University. He joined University of Sydney in July 1992 after working as an Alexander von Humboldt Fellow at the Institute for Composite Materials (IVW GmbH), 1990 to 1992. He was Head of the School of AMME for a period of four years, 2004 to 2007. His research publications include 3 research monographs, 5 edited books, 10 book chapters and over 380 refereed scientific articles in leading journals as well as more than 30 plenary, keynote and invited lectures presented at major international conferences. Most of his research papers have been published in the top journals in his field including Composites Science & Technology, Composites Part A, etc. His major research interests are in the areas of composites science and technology, smart materials and structures, nano-materials and nano-composites, structural integrity and durability. He has supervised 28 PhD and 12 MPhil students, and over 30 postdoctoral research fellows/associates and visiting scholars in AMME, University of Sydney. He was elected a Fellow of the Australian Academy of Technology and Engineering (ATSE) in 2005.

Nonlinear behaviors of wave-induced fluid oscillations in the gap between two fixed barges.

Abstract:

Extremely large amplitude of resonant wave oscillation is often encountered in the narrow gap between two floating bodies.

New devising in diagnosis of knee osteoarthritis based on acoustic emission imaging

Abstract:

Acoustic emission (AE) technique has been applied in devising an adaptive imaging tool for evaluating the integrity of knee joint, which involves a detail study of several anatomical parts of knee joint like bones, cartilage, tendons etc. Any internal damage of these anatomical parts of knee joint causes painful disease like osteoarthritis (OA). The major concern of this disease is the incurability at its matured stage. However, early detection for adopting appropriate measures can reduce the risk of this disease. The present discussion will focus on the characterization of this new devising technique in dynamical behavioral analysis of AE signals from knee joint for easy diagnosis of knee problems in aging as well as other causes. Cases will be discussed based on data from OA participants as well as healthy people.
Keywords: Integrity of Knee Joint, Osteoarthritis, Acoustic Emission, Biomarker.
