Abstract : One-, 2-, and 3-3/8-inch-thick plates were cold-formed in a submarine yard to the predicted minimum bend radii. The results of the cold forming showed that the actual bend radius at the onset of cracking was about the same or slightly smaller than the predicted minimum bend radius. Thus, the Laboratory procedure is quite reliable for estimating cold formability under conditions of plane strain, the state-of-stress that generally exists during cold forming of wide plates. Moreover, because the bend radii at the onset of cracking were smaller than those normally required for submarine-hull fabrication, the 5Ni-Cr-Mo-V steel has more than adequate ductility for submarine-hull fabrication.
