Assessment of Long-Range Reliability of Ceramic Products
Fracture mechanics provides the foundation necessary for making failure predictions to assure the reliability of ceramic materials in structural applications. The parameters necessary for making these predictions can be obtained directly from crack velocity measurements or, indirectly, from stress rupture or stressing rate experiments. These techniques of predicting the lifetime of ceramic components have been tested experimentally for several materials and agreement between theory and experiment is good. The application of this theory to assuring the lifetime of a ceramic product is described.
