Determination of Stress Distribution in Fibre Bridged Cracks in Ceramic Matrix Composites

[摘要] Laser Raman Spectroscopy is being used to characterise interfacial properties and stress concentration in bridging fibres of a glass ceramic matrix composite. The preliminary results show that the stress distribution along fibres can be mapped. This technique will therefore assist the understanding of the fracture and fatigue behaviour of these materials.
