In ceramic materials, the fracture resistance can increase as a function of the crack length. Such behaviour is beneficial, e.g. in terms of the thermal shock resistance. It is termed R-curve behaviour and reflects the capacity of the material for intrinsic and/or extrinsic toughening during stable crack advance. Another design-relevant material-specific property is the sensitivity towards subcritical crack growth. The latter is a time-dependent phenomenon and commonly estimated by two crack growth parameters. The presented paper aims for a detailed review of sequential fourpoint bending experiments on V-notched beams, which are used to evaluate both phenomena from a single measurement. Three groups of materials (Al2O3, Si3N4, and Lithosil glass) were tested and analysed by this method in order to provide an experimental data background.en0955-221920255Elsevierhttps://creativecommons.org/licenses/by-nc-nd/4.0/AluminaFour-point bendingR-curveSilicon nitrideSubcritical crack growthTechnology::620: Engineering::620.1: Engineering Mechanics and Materials Science::620.11: Engineering MaterialsJournal Articlehttps://doi.org/10.15480/882.1632610.1016/j.jeurceramsoc.2025.11805110.15480/882.16326Journal Article
