The fracture‐of alumina disks subjected to thermal shock is predicted from Weibull parameters derived from isothermal three‐point‐bend tests. Both the shear‐insensitive Batdorf model and the principle of independent action model are used to compare results from three‐point‐benr1 and isothermal biaxial strength tests to results from thermal fracture tests. It is found that the shear‐insensitive Batdorf model gives good agreement between mechanical tests and fracture of the thermally shocked disks.
