Thermal shock of ceramic material : Damage resistance parameters and critical flaw size
Abstract
The alumina refractories used in this study included a serias of 12 commertial products (two fireclay and ten high alumina brands ) containing ≈ 45 - 90 % Al2O3. Damage resistance parameters R,, R, and RSt were used in this paper. Critical flaw size was calculated from the fracture toughnesses of the chosen materials. Calculated values of damage resistance parameters were compared to critical flaw size, (YCcrit1/2). Statistical analysis was used to determine the corelation between the R parameter and the critical flaw size. Results of the regresion analysis showed a linear dependence of the damage resistance parameter R, on the critical flaw size. Linear dependences were also obtained for the comparison R, and RSt parameters on the critical flaw size, but coeffitient of corelation were less satisfactory.
