However its interpretation is complex for cylindrical supports due to their irregular geometry and the various fracture modes induced. A better analysis of the crushing test, altogether with a comparison of the results obtained with the three-Point Bending test (3PB) and an analysis of the defects present within the supports, provide a better interpretation of their crushing strength data. Experimental results show that two different fracture modes appear during the crushing test – one under bending configuration and one under crushing configuration – inducing a large scatter of the data. Moreover, a comparison with the 3PB test shows that the strength measured in crushing is lower and the scatter of the data is larger than the ones obtained in bending. This is a consequence of a Weibull size effect and of the presence of macro-defects within one type of the tested supports. It is concluded that an analysis of the fracture modes activated during crushing has to be carried out to obtain a correct distribution of the strength data. The presence of macro-defects within the microstructure of the supports decreases drastically the crushing strength, while their influence on the bending strength is more limited. 3 Oil and Gas Science and Technology 70 ARTICULO Staub, D. 54916 Meille, S. 54917 Le Corre, V. 54918 Chevalier, J. 54919 Rouleau, L. 54906 189213 189213 0 0 0 0 257032 BAAB BAAB 2026-03-06 200061445 0 200061445 2026-03-06 00:19:25 2026-03-06 ARTICULO
