These results support the conclusion that with a load higher than 6000 N, a defect arises and develops in the vicinity of the first sensor, which in the case under consideration has the nature of material failure along the ridge of the specimen. The readings of the first and second sensors and visual inspection show that the appearing defects are distributed unevenly along the ridge of the specimen. This is a consequence of the impossibility of providing in a real experiment the symmetry of the geometry and loading conditions with respect to the central section of the ridge.
