Three-point bending specimens were tested in a INSTRON-1275
servo-hydraulic machine, using the same load cell already
described in the direct tension tests. The CMOD (Crack Mouth
Opening Displacement) was measured using the same EPSILON
clip gauge already mentioned in the torsion tests. In this case, load
was applied through CMOD control, at a constant rate of 0.01 mm/
min.
