MEASUREMENT OF RESIDUAL STRESSES IN WELDED SHIP STRUCTURES AND THEIR EFFECT ON THE STRENGTH OF THE STRUCTURE

A good solution for the determination of the state of residual stresses in real structures is to employ only such measuring procedures as do not impair the bearing strength of the structural member at all, or only to a negligible extent. The hole-drilling strain gauge method and the hole-drilling method with embedded pellets and measuring with the contact type strain gauge are suitable for such measuring operations. Measurements on I-girders showed the hole-drilling strain gauge method to be of advantage. It delivers satisfactory values even when compared with the more exact measurements obtained by the splitting-up method. A description is given of the evaluation of the state of welding residual stresses in the longitudinal framework of a ship.
