The fracture toughness is in this group of material rather low, therefore a variety of reinforcements incorporated in the ceramic matrix is used to enhance strength via increased fracture toughness. The other way how to increase strength is to minimise the size of defects creating during processing. The combination of both is very demanding task. The layered structure possess an advantageous alternative for applications where such type of structure is possible e.g. microelectronics systems, highly loaded parts, biology etc.. The layered structure allows tailoring of properties according to the application needs and can enhance the stiffness, strength and fracture resistance together. In this contribution materials with strongly bonded layers having controlled internal stresses in the layers are discussed in detail. The use of tailored internal compressive/tensile stresses is a key parameter to adjust mentioned properties together with the optimal design of layers, i.e. creating strong and flaw tolerant materials. The internal stresses are governed by the targeted phase transformation, thermal expansion mismatch of neighbouring layers and the total amount of individual constituents. The theoretically based analyses both analytical and numerical are explored and fracture mechanics is applied for prediction of the crack behaviour. All these predictions applied in the design of layered materials allows preparation of materials having given minimal strength (deterministic) what is in the ceramic materials generally unusual feature.
