| Abstract Scope |
Ceramics composites are designed for improved fracture toughness compared with monolithic ceramics. They often have complex microstrucutre therefore in-situ imaging technqiues are needed to investigate their deforamtion, crack initation and propagation in 3D. This work will showcase a range of composites for nuclear and aerospace applications studied using in-situ X-ray computed tomography with loading at elevated temperatures up to 1200°C. The loading configurations include three point bending and notched flexural testing. The tests were carried out over a range of temperatures and the impact of temperature on the mechanical behaviour of the different types of designs will be reported. Post-test data analysis inlcudes 3D image segmentation as well as digital volume correlation for 3D strain distribution to identify the 3D failure strain, strain localisation, crack initiation and propagation. The toughening mechanisms in the materials systems will be presented. |
