Melikayeva, H. Riesch-Oppermann, V. Govorukha, O. Kraft] Due to the inherent brittleness of ceramics, the reliability of ceramic components is evaluated using the Weibull theory. Hence, the failure probability due to the presence of surface or volume flaws is calculated using a suitable fracture mechanics approach. In the following paper, the weakest link approach is generalized for the case of bi-material ceramic joints. Here, interface cracks need to be considered for causing failure. Interface failure probability is found to be a function of the crack tip mode-mixity state. This influence is assessed in the general loading case for a bi-material strip with an internal interface crack. Under certain conditions, a simplified analysis is possible, leading to a conservative assessment of the failure probability for interface cracks in a gradually varying remote stress field.
