Page 59 - Furthermore, no ductility was displayed by either after rupture, which shows conclusively that the properties exhibited by the longitudinal static tensile specimen were not utilized previous to failure. (9) The ordinary tensile tests showed a complete lack of ductility at right angles to the axis of the screw.

Page 59 - Our present knowledge would, therefore, lead us to conclude that brittleness would be experienced at right angles to the principal axis. The unnotched Charpy tensile specimens, taken at right angles to the axis of the screw, verify this conclusion.
