Abstract
The residual stress program at DREA has been designed to obtain an understanding of the level of residual stress on an operational submarine and to determine the most effective method of obtaining the field data. The entire program involves the comparison of the blind-hole drilling technique, the X-ray diffraction technique and the neutron diffraction technique. The blind-hole drilling technique has been used to determine the stresses on damaged hull sections, test welds and at many locations on the hull including original weldments and recent inserts. The effect of surface finish on the level of residual stress has been studied. A new blind-hole drilling apparatus has been designed and built for use in areas near forms. A description of the comparative on going study of the blind-hole drilling, X-ray diffraction technique and the neutron diffraction will be given. Typical results of actual hull stresses will be given. TRUNCATED
