The single‐edge V‐notched‐beam (SEVNB) testing geometry was used to measure the crack growth resistance ( R ‐curve) behavior of multilayered alumina–zirconia composites. Fracture mechanics weight function analysis was applied to predict the R ‐curve behavior of multilayered composites having a stepwise change in composition. These results were then used to differentiate the influence of residual stresses from crack‐bridging stresses on the measured R ‐curve behavior.
