Mechanical characterization of structural ceramics
Ceramics currently receive much interest as possible candidate materials for structural applications at high temperatures. This is due to a combination of favourable properties amongst which high temperature strength, corrosion and erosion resistance are the most prominent. These advantageous properties of ceramics are offset, however, by their brittleness, strength variability and susceptibility to thermal shock failure. In this set of two lectures, the life limiting mechanisms occurring in monolithic ceramics are described. A differentiation is made between defect initiated damage or failure mechanisms, and other mechanisms. This is followed by a discussion of the experimental methods available to engineers and material scientists to characterise the mechanical behaviour of these materials. Particular attention is paid to the requirements that the mechanical testing methods have to meet in order to obtain relevant test results.
