GEOMETRIC EFFECTS OF PLATE THICKNESS
The results of the investigation can be summarized as follows: (1) The van der Veen test, the Bagsar test, and the drop-weight test showed general agreement in their response to changes in plate thickness ranging from 3/4 to 3 inches. (2) The dimensional effect of plate thickness, with metallurgical variables held constant, was to raise the transition temperature markedly as the plate thickness was increased from 1/2 to 1-1/2 inches. Above 2 inches, thickness appeared to have much less effect on the transition temperature observed in these sharply-notched specimens. ABS Class C and "T-1" steels behaved similarly in this respect. (3) In the presence of a severe notch, specimen widths and heights of 2 inches or greater appear adequate to determine the sensitivity of heavy-section steel plate to brittle fracture. (4) The van der Veen specimen is recommended as the testing method for the second phase of the program because of its testing convenience and its suitability for determining transition temperatures by a variety of criteria.
