Rapid changes in ambient temperature (thermal shock) induce stress in a         material.,  For brittle components, these thermal stresses can result           in microcracking or mechanical failure.  The objective of this research         is to use elasticity measurements to assess damage due to the multiple          (repeated) thermal shocking of ceramics, using both liquids and gases           (including air) as quenching media.  Unlike fracture testing, these             nondestructive elasticity measurements allow one to monitor the                 evolution of thermal shock damage due to repeated thermal cycling.  The         significantly higher precision of the elasticity measurements compared          to fracture measurements will allow accurate determination of the               successive degradation of the ceramic upon thermal cycling, especially          at the initially low levels of thermal shock damage.
