title = "Experimental R-curve behavior in partially stabilized zirconia using moir{\'e} interferometry",
abstract = "Moir{\'e} interferometry is employed to study toughening in partially stabilized zirconia (PSZ). Energy to fracture as a function of crack growth curves (R-curves) is derived from mode I compliance calculations and from near tip fitting of the moir{\'e} fringes. The effect of the tetragonal to monoclinic phase transformation in the zirconia is found by comparing the bulk compliance R-curves to the locally derived moir{\'e} R-curve. Localized strain field plots are produced from the moir{\'e} data for the PSZ zirconia. The observed transformation zone height compares favorably with that predicted by Okada et al. [Acta metall. mater. 40, 1421 (1992)] in a companion paper, as does the qualitative nature of the R-curve with predictions by Stump and Budiansky [Acta metall. 37, 3297 (1989)].",
