Towards mussels under stress: Novel concepts to design hierarchical architectures with high reliability and high fracture resistance
Original language description
In this paper, novel concepts are presented which combine different approaches used in layered architectural design with strong interfaces aiming to obtain highly reliable ceramic materia ls with high fracture resistance. On the one hand, the use of tailored residual stresses in embedded layers within the structure is demonstrated to act as an effective barrier to the propagation of surface flaws, providing a minimum design strength for the material, below which failure cannot take place [3]. On the other hand, texturing of the microstructure in embedded layers is utilized to provide preferential paths for conducting propagating cracks (Fig. 2), thus protecting the underlying structure [4]. In addition, recent work has shown that the combination of layers in a non - periodic manner can be more effective in arresting the propagation of cracks than the commonly used periodic designs [5].The location and thickness of the layers designed with compr essive stresses can be optimized to maxim
