Cracking of Simple Structural Geometries

This report presents the results of an investigation concerning the general subject of the cracking of simple structural geometries under tensile loading. A summary is given of the effects of edge notch geometry and the effects of interrupted longitudinal members which were previously reported in Progress Reports I and II of this project, whereas the effects of edge preparation, the effects of fastenings, and the effects of welded pads are reported in their entirety for the first time.
