The high incidence of serious fractures in the hull plating of welded steel merchant ships, in World War II, led to a number of laboratory investigations of the causes of cleavage fracture in structural steel plates. The tests on flat plates which most nearly represented the field conditions found in ships decks were those conducted at Illinois and at California. They consisted of static tension tests of specimens cut from 34-in. plates to widths varying from 12 in. to 72 in. Each specimen contained a severe internal stress raiser consisting of a transverse slot across the middle one-fourth of the width of the specimen, ending in a jewelers saw cut. It was found in these investigations that strength decreased with increasing specimen width and approached the yield point of the plate material for the 72-in. specimens.
