Effect of residual stresses to the crack path in alumina/zirconia laminates
Original language description
Laminates with alternating layers are well known from nature. The strongly bonded alumina/zirconia (Al2O3/nZrO2) layers can combine high fracture resistance with high strength and stiffness when properly tailored. Thenpresence of compressive residual stresses formed in Al2O3 layers can suppress and deflect cracks propagatingnthrough the layers. The crack path is governed by both the elastic properties and the internal stress field ofnindividual layers. The laminates with various layer-thickness ratios ranging from 0.1 to 3 were used to investigatenthe effect of residual stresses and influence of crack formation pattern on the crack path development.nThe indentation surface cracks observed in various alumina-zirconia laminates exhibit the same crack deflectionnindependently on the level of internal stresses. The crack deflection observed on the fracture surfaces of bendingnspecimens was related to the indentations cracks. The complicated crack path was explained experimentally byn3D reconstruction with the support of numerical simulations.
