Thermal Shock Behaviour,ceramic components, high thermal stresses are generated which are responsible for the extension of existing cracks. Whereas in metals the temperature gradients only cause small plastic deformations, in the case of ceramics with its linear elastic material behaviour high stresses are generated. As a

Special chapters are devoted to creep behaviour, multiaxial failure criteria and thermal shock behaviour.978-3-642-63580-9978-3-642-58407-7Series ISSN 0933-033X Series E-ISSN 2196-2812

This is also the reason for a pronounced influence of the component size on strength. The lifetime of ceramics undergoing subcritical crack extension also shows a large amount of scatter, which can be related to the scatter of the strength.
