Weight function analysis on the R-curve behavior of multilayered alumina-zirconia composites
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.
