In-situ investigation of fracturing of porous ceramics under high strain rate compression with SHPB systems

3d printed porous ceramics materials have recently been revolutionized with the ability to sustain high mechanical loads and present themselves as rapid solutions in many industrial fields exposed to dynamic and high cyclic fatigue environments. Some notable examples are related to the airspace industry and bone tissue engineering. However, they still suffer from sudden failure and abrupt fracturing modes, to investigate how designed porosity content can stimulate such behavior and how it might be mitigated, direct t observation of fracturing at pore-scale is needed under representative loading conditions. In this work we will conduct a proof of concept on two such ceramics using SHPB setup and high-speed X-ray imaging of id19 to directly observe the interaction of fracturing, fragmentation and pulverization with respect to different porosity content.
