Crack path prediction in layered ceramics designed with residual stresses.
Original language description
In this work a computational tool, aiming to predict the crack propagation (i.e. straight propagation, single deflection or bifurcation) on layered ceramics designed with internal residual stresses, is developed. They consist of two material layers withdifferent properties, alternated in a multilayer structure. The internal stresses developed during sintering are associated with the volume ratio of both materials, i.e. V1/V2. The computational model is based on Finite Fracture Mechanics theory, especially focused on cracks terminating at the interface of the two different material layers. The method utilizes a matched asymptotic procedure to derive the change of potential energy associated with the fracture process. A combined loading (thermal and mechanical) is taken into consideration to clarify the influence of the residual stresses on the crack path during fracture. The crack paths predicted by the model are compared and discussed with experimental observations on layered ceramics
