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

An energetic approach to characterise fracture of soft matter by cutting. Cutting of soft materials is a common daily life experience (e.g. slicing of meat and cheese) and an essential operation in many industries, healthcare (e.g. surgery) and manufacturing (e.g. paint removal) among them.
