Tailoring the Mechanical Behaviour of Ceramic Laminates Using a Non-Periodic Multilayer Architecture

Popis výsledku v původním jazyce

The low resistance to crack propagation, flaw-size dependence of strength and poor damage tolerance have limited the use of monolithic ceramics as advanced engineering materials for certain applications. Much progress has been made to design ceramic composites to improve fracture toughness. At the macroscopic scale, composite materials can be arranged according to various configurations (i.e. connectivity [1]), such as the 2-2 symmetric laminate composites which consist of alternate layers of differentcompositions ordered in a periodic architecture. These structures provide the opportunity for tailoring the properties by designing composite build-up strategies [2]. 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. The location and thickness of the layers designed with compressive stresses can be optimized to maximize the crack growth resistance of the multi
