| Abstract: | 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. |
