Self-Driven Cracking by Crack-Face Cooling During Thermal Shock Testing of Ceramics
Temperature changes during service are normal in many industrial applications of ceramics. Previous work had shown that simple fracture mechanics give good estimates of the extent of cracking in most cases and suggests that full penetration of a refractory brick should not occur. This paper shows that liquid penetration can initiate a new cracking mechanism, in which a crack can drive itself because of the additional cooling and grow fully through a brick, leading to a loss of containment. Led to collaborations (£100k) with Morgan Thermal Ceramics (UK,Paul.Myers@morganplc.com) and Kerneos (France, chris.parr@kerneos.com) on refractories.
