The crack growth resistance of the composites is assessed by means of their R-Curve behavior determined by three-point bending tests on single edge \u201cV\u201d _notched beams (SEVNB), in two different orientations of the samples: with the crack path perpendicular or parallel to the pressure axis during the SPS sintering. The sharp edge notches were machined by ultrashort laser pulsed ablation (UPLA). The compliance and optical-based methods for evaluating the crack length are compared on the basis of the experimental R-Curve results in composites with 2.5 vol% rGO tested in the perpendicular orientation. Moreover, the activation of reinforcement mechanisms is evaluated by both the fracture surface inspection by Scanning Electron Microscopy and a compliance analysis. It is shown that the indirect compliance method is relevant and reliable for calculating the R-Curve of 3YTZP\/GBN composites. The effect of the type and content of GBN on the crack growth resistance of the composites is also discussed.<\/p><\/div><\/div>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t<section class=\"elementor-section elementor-top-section elementor-element elementor-element-d0e7233 elementor-section-boxed elementor-section-height-default elementor-section-height-default\" data-id=\"d0e7233\" data-element_type=\"section\" data-e-type=\"section\">\n\t\t\t\t\t\t<div class=\"elementor-container elementor-column-gap-default\">\n\t\t\t\t\t<div class=\"elementor-column elementor-col-100 elementor-top-column elementor-element elementor-element-fbf9f30\" data-id=\"fbf9f30\" data-element_type=\"column\" data-e-type=\"column\">\n\t\t\t<div class=\"elementor-widget-wrap elementor-element-populated\">\n\t\t\t\t\t\t<div class=\"elementor-element elementor-element-fec359a elementor-widget elementor-widget-text-editor\" data-id=\"fec359a\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<p style=\"font-family: Raleway, sans-serif; font-size: 16px; text-align: justify;\">More information at:<\/p><div class=\"csl-bib-body\"><div class=\"csl-entry\"><div class=\"csl-bib-body\"><div class=\"csl-entry\" style=\"text-align: justify;\">L\u00f3pez-Pern\u00eda, C., Mu\u00f1oz-Ferreiro, C., Prada-Rodrigo, J., Moreno, P., Reveron, H., Chevalier, J., Morales-Rodr\u00edguez, A., Poyato, R., &amp; Gallardo-L\u00f3pez, \u00c1.
