Perpendicular preload

The specimens were positioned carefully between the pistons of a universal testing machine using a positioning aid to guarantee that the load is applied perpendicular to the notch plane. Then a preload was applied (about 10 % of the estimated fracture load). Then the aid was removed and the load was increased until fracture. The loading rate was selected in such a way that a test can be done within 10 to 20 seconds. The fracture load was used to determine strength (eq. I). [Pg.331]
