A number of studies on the thermal shock behavior of finite-thickness slabs with the temperature varying through the thickness have been conducted over the years by researchers such as Albrecht 1, Chen 2, and Nied 3, to name just a few. However, a review of these solutions reveals that the transient thermal loading is usually restricted to either a step or linear function of time whereas many thermal shocks are asymptotic in form (Vedula et al. 4 and Tu and Segall 5). Consequently, the actual time and magnitude of the maximum stress may vary significantly from an overly conservative prediction based on...
