It is found that crack-healing can eliminate the pre-crack under stress below 64% fracture stress of the cracked specimen, if the ceramic components have an adequate crack-healing ability.
The use of FE techniques for calculation of the fracture in loaded ceramic inlays offers prospects for further detailed study of the crack behavior, including three-dimensional modeling and cyclic loading situations
These cracks provide a high degree of strain tolerance to the ceramic top coat.
The presence of edge cracking, or its incipience, is thus concluded to be critical to the occurrence of crack bifurcation in laminar ceramic composites.
The main conclusions were obtained as follows: (a) Mullite/SiC composite ceramic has ability to heal crack.
The cracks are healed and the specimens are tested under bending. Findings – The paper finds that ZrO2/SiC composite ceramic material had a high crack‐healing ability at a considerably low temperature.
These observations may be applied to the problem of ‘crack-stopping’ in certain ceramic materials.
This paper quantitatively studies the thermal-shock crack growth of ceramic in real time and expands the scientific understanding of thermal shock cracking phenomenon of ceramic.
These crack patterns are very useful to understand the failure mechanisms of ceramic materials in thermal shock.
The present study leads to an improved understanding of the formation and evolution of thermal shock crack patterns in ceramics and can help engineers to assess the thermal shock failure of practical ceramic components.
