“…glasses, ceramics) [27][28][29], and has also been applied to cemented carbides [23,30,31], and even metal alloys [32], due to some advantages compared to the most common standardized tests, such as 3-point and 4-point bending. Specifically, the main advantages include ease preparation of test samples, high tolerance for some out of flatness of the disc and/or misalignment, much lower friction than in the other common tests, possibility of using small test specimens (even with irregular shape and closer to the real workpiece geometry), absence of tensile loaded edges, among others [23,25,27,28,33]. The main disadvantage of the B3B method is that the load is concentrated in a very small location of the sample and, thus, larger critical defects may not be sampled during the tests.…”
