“…This result is lower by 45% than the K IC measured on notched beams geometry and the difference is cause by the geometry effect. This geometry effect was recently discussed for lime stone, 23 for C 50/60, 16 for normal strength concrete (NSC) and high-strength concrete (HSC). 24 To evaluate the fracture resistance curve of the HPC under the mixed I/II, BDCN specimens were tested with various inclination angles a.…”

“…Recently, it was shown by researchers in 16 that the r C for C 50/60 could also be used for plane-strain boundary conditions in whole fracture process, i.e., r C = 1.559 mm. In the work 17 , the r C was 1.38 mm and 2.54 mm for the low-strength mortar and concrete, respectively.…”

This paper reports and discusses the results of an experimental investigation into the fracture mechanical properties of high-performance concrete (HPC) with a compressive strength higher than 100 MPa. In total, 6 specimens for a three-point bending test and 12 specimens of a Brazilian disc under a mixed-mode load were included in the experimental measurements. The fracture toughness was evaluated for mode I in the case of a three-point bend test and a Brazilian disc test, allowing a correlation between two geometrically different specimens. The fracture resistance under mixed mode I/II was analysed using the Brazilian disc test specimen with a central notch. To evaluate the fracture resistance under the mixed mode a generalised maximum tangential stress criterion was employed and the value of the critical distance rC is discussed as an appropriate HPC material characteristic. The last objective of this study was to provide some experimental data that can be useful in engineering practice for calibrating numerical constitutive models.Avtorji poro~ajo in razpravljajo o eksperimentalnih raziskavah lomno-mehanskih lastnosti visokokakovostnega betona (HPC; angl.: High Performance Concrete) s tla~no trdnostjo nad 100 MPa. V kompletu so izvedli trito~kovne upogibne preizkuse na {estih (6) vzorcih in na dvanajstih (12) vzorcih v obliki diskov so izvedli brazilski preizkus, ki predstavlja me{ano (natezno/tla~no) obremenitev. Dolo~ili so lomno`ilavost za na~in I v obeh primerih; to je trito~kovnega upogibnega preizkusa in brazilskega testa, upo{tevajo~geometrijske lastnosti obeh vrst vzorcev. Odpornost proti lomu v me{anem na~inu I/II so analizirali s pomo~jo brazilskega preizkusa na vzorcih (diskih) s centralno zarezo. Da bi ovrednotili odpornost proti lomu v me{anem na~inu, so uporabili posplo{eni kriterij maksimalne tangencialne napetosti in ocenili, da je vrednost kriti~ne razdalje primeren kriterij za oceno lastnosti HPC. V zadnjem delu te {tudije so podali nekaj eksperimentalnih podatkov, ki bi lahko bili uporabni v in`enirski praksi za kalibracijo numeri~nih konstitutivnih modelov.

“…Brazilian disc test with a central notch (BDC) is specimen with circular cross section, made from the cylinder with a notch in the middle of specimen (see Figure 1a) [8][9][10]. The test performed on the BDC specimen is carried out under relatively simple experimental conditions (see Figure 1b), using only the testing press with sufficient load capacity.…”

Nowadays, high performance concrete is used more frequently because of the many advantages compared to traditional concrete. The higher mechanical properties (e.g., compressive strength, flexural strength, and Young's modulus) allow for larger spans and slender cross-sections. Despite the use of advanced material, standards for structural design do not fully use materials' potential. This can be minimized by using fracture mechanical properties in structural analysis. The fracture mechanical properties help to perform advanced structural analysis, especially when some of the structural elements have a crack. The load presence on the structure can be divided into tensile-mode I, shear-mode II, and combination of tension and shear-mixed mode I/II load. Therefore, it is necessary to perform test, which covers mixed mode loading conditions. One of the tests usually used for the evaluation of fracture resistance of concrete is Brazilian disc test. This contribution compares fracture resistance of two types of structural concrete (normal and high strength) under the mixed mode I/II. The generalized maximum tangential stress (GMTS) criterion was used for the evaluation of the fracture resistance.
