Investigation of Thermal Shock Resistance of Ceramic Materials Under Programmed Heating
The report describes the equipment and test method for the thermal stress resistance of ceramic hollow cylindrical specimens under programmed heating conditions. The experimental data are recorded with the use of a computer. The analysis of the state of thermal stress of the specimens for elastic and nonelastic materials has been conducted, and the dependence of thermal shock resistance of ceramic materials upon their brittleness has been demonstrated. The relationships between the optimum thermal loading condition and specimen size have been established. The expedience of using the described technique in statistical investigations of ceramic materials is demonstrated.
