The Deep hole drilling (DHD) technique has received much attention as a measurement method for through-thickness residual stress. In the past, however, the traditional DHD technique has ignored the effects of plastic deformation around a reference hole, which has been occurred in the DHD procedure. Therefore, the evaluation results obtained by the traditional DHD technique can have accuracy problem. When residual stress is large, the problem is serious because the area which deform plastically. In this...
英字タイトル:
