Abstract The purpose of this project is to develop a technique for identifying and quantifying damage in fibre composite structures using infra-red measurements. The technique will make use of conventional IRT and TSA. The IRT will enable the measurement of the cumulative temperature variation and TSA will be used to monitor the localised stress variations that occur as a result of damage accumulation. Intensive measurements will be made at various stages of the material s fatigue lifetime to measurethe material properties at appropriate damage states. Key factors to be investigated will include the point at which the assumption of reversible temperature change within the TSA analysis begins to break down and the extent to which material damping changes with the onset of damage. The combination of the two techniques will provide a much-improved understanding of the behaviour of composite materials under fatigue loads. A major part of the proposal is to model the material behaviour usingfinite element techniques and in particular any thermoviscoelastic processes, and then to use the model as a predictive tool. The ultimate goal is to develop a damage parameter based on TSA/IRT readings and incorporate this into the Deltatherm software. The approach will then be validated on a large FRP structure.
