Abstract

Results are presented for the effect of spatially varying thermal conductivity on the tensile thermal stress developed in a solid and a hollow circular cylinder subjected to different heating conditions. It is shown that the maximum tensile thermal stress in brittle ceramics can be reduced significantly by redistributing the temperature profile using a spatial variation in thermal conductivity; a spatial variation in pore content which in turn changes the density, thermal conductivity and modulus of elasticity; and by considering the effect of temperature on the thermal conductivity and specific heat. Possible methods for creating such variations in the material properties are discussed.
