A method of treating spalling failure during initial heat‐up is presented. The assumptions include very high rates of convective heating, failure at hot surfaces from shear stresses, statistical failure, and failure defined by multiple crack intersection. On the basis of this and other work, it is concluded that scale‐model tests are, in general, inappropriate.
