Strategies to Optimize the Strength and Fracture Resistance of Ceramic Laminates

Popis výsledku v původním jazyce

Layered ceramics, compared to conventional monolithic ceramics, are good choices for highly- loaded structural applications because they exhibit greater fracture resistance, higher strengths and better mechanical reliability (i.e. they are flaw tolerantmaterials). The use of tailored residual compressive stresses in the layers is a key parameter to adjust these properties. In this work ceramic laminates are analyzed which have internal residual compressive stresses. The most important factors having influence on the strength and fracture resistance of these laminates are discussed. A fracture mechanics analysis is employed to estimate the crack growth resistance of the material as a function of the crack length. It is found that the proper selection of a suitable strain mismatch (responsible for the generation of residual stresses), volume ratio of the layer materials and thickness and distribution of individual layers are crucial to achieve a high fracture resistance and/or a high lo
