Abstract: A process of crack appearance and growth inside brittle ceramics materials while their heating was investigated with mathematics methods. Humid (concrete) and dry (burned ceramics) were taken as modeling objects and both rapid and slow temperature changing were discussed. This investigation needed a new approach to modeling of material pore structure, so several special algorithms, based on finite element and cell automata methods were prepared specially for this study. Models were verified with several real objects - refractory linings of apparatus of steel metallurgy.
Brief Biography of the Speaker: Andrew V. Zabolotsky was born in St. Petersburg, Russia in 1975. He had graduated from St. Petersburg State Institute of Technology (Technical University), department of High-Temperature Materials in 1998. He had defended a thesis about technology of silicon nitride (SIALON) ceramics and received PhD degree in technical sciences in 2002. After graduating he worked at JSK “Sigma-T” (2000-2002) – a producer of high-temperature testing equipment for ceramics and refractory materials as a head of heat insulation department. Between 2002 and 2004 he was a technologist at laboratory of “Refractory technologies ltd.”, a company which produced refractory concrete for iron and steel industry. At the present time he is an engineer-technologist of “Magnezit Group ltd.” – one of the main producers of periclasse-carbon refractory materials in Russia. He had prepared and published more than 50 papers for different journals in Russia and other countries. He was a participant of several international conferences (for example IAS Conference in 2009 at Buenos Aires, Argentina, Moscow conference of refractories and metal producers (2010), Kiev mathematics conference (2010)). At the present time he is working with problems of heat exchange and thermal failure in refractory linings of metallurgical installations. Main interest at the present time is in building forecasts of refractory linings failure with help of mathematics and statistic methods.
