This project plans to investigate a novel approach for in situ measurement of stress in structures based on an internal resonance phenomenon for nonlinear guided waves. Monitoring the stress level of critical structural components is important to ensure structural safety. The project plans to derive the requirements for this internal resonance and its dependence on stress analytically and verify them experimentally for both simple waveguides and more realistic structures. The expected outcome is the demonstration of the feasibility of a new inexpensive method for continuous monitoring of applied or thermally-induced stresses, which is of great importance in several engineering contexts, such as modern railway track rails, pipelines or pre-stressed strands in concrete structures.Read moreRead less
Investigation of Thermotransport in Liquid Metal Alloys. This project aims to improve understanding of thermotransport to support the use of liquid metal allows in manufacture and energy transfer. The coupled flow of heat and mass (thermotransport) rapidly produces segregation in liquid metal alloys in a temperature gradient. This is a major problem in optimising the solidification from melts in manufacturing and for the design of liquid alloys for transfer of heat. Thermotransport is very poorl ....Investigation of Thermotransport in Liquid Metal Alloys. This project aims to improve understanding of thermotransport to support the use of liquid metal allows in manufacture and energy transfer. The coupled flow of heat and mass (thermotransport) rapidly produces segregation in liquid metal alloys in a temperature gradient. This is a major problem in optimising the solidification from melts in manufacturing and for the design of liquid alloys for transfer of heat. Thermotransport is very poorly understood. The project aims to achieve an understanding of the process through a combination of new theory, corresponding new experiments and advanced computer simulations. This would be a major advance in the area, supporting the development of new systems to prevent segregation.Read moreRead less
