Thermal Stresses in the Thin Circular Disk When the Thermal Conductivity is Temperature Dependent

摘要

Thermal stresses are determined and compared for temperature distributions in a thin circular disk resulting from both constant and temperature dependent thermal conductivities. If the disk is heated at the edge, the stresses are reduced when the thermal conductivity increases with an increase in temperature. On cooling, the stresses are reduced when the thermal conductivity decreases with an increasing temperature.
