Stashnikova M. Simulation of heat conductivity processes in thermal stability calculations and determination of thermophysical characteristics of complicately shaped crystals.

The object of study. Single crystals. The aim of study. Thermal stability calculations and determination of thermophysical characteristics. Methods. Basing on solution of heat conductivity and thermoelasticity equations. Theoretical and practical results, newness. It has been established that the power temperature dependence of heat conductivity results in qualitative changes of the temperature and stress distribution. The thermal stability can be estimated with a sufficient accuracy by way of calculation, providing the data on the material properties are full enough. A thermal shock causes short-time dynamic stresses in solids. In bilayer systems subjected to severe thermal actions, it is just the layer interface that has been established to act as a concentrator of maximum stress. Degree of practical application. The result are used in Institute for single crystals, NASU, Kharkiv. The sphere of application. Scintillation detectors. 6156
