Estimation of apparent fracture toughness of ceramic laminates
Original language description
The paper presented deals with the fracture behavior of ceramic laminates. The residual stresses in individual layers of Al2O3/5vol.%t-ZrO2 (ATZ) and Al2O3/30vol.%m-ZrO2 (AMZ) are determined. Assumptions concerning linear elastic fracture mechanics and small scale yielding are considered. In this frame the procedure based on a generalization of Sih?s strain energy density factor to the case of a crack touching the interfaces between two dissimilar materials is used for determination of effective valuesof the stress intensity factor on material interfaces. An important increase of fracture toughness at the AMZ/ATZ interface was predicted in comparison to the fracture toughness of individual material components. Predicted values were compared with dataavailable in the literature and mutual good agreement was found.
