LARGE PERMANENT SET OF SHIP BOTTOM PLATING DUE TO SLAM LOADS

It is the aim of this paper to develop a method for determining the large permanent set of bottom plating caused by large slam loads. The theoretical analysis is carried out in two steps; first, the case of large permanent set due to only large slam load and second, the case of a large slam load applied many times. In carrying out the former, the same assumptions and principles as those used in the previous paper are reintroduced and the effect of stretching is included as well as that of bending, but in the latter case, another theorem about the limit analysis and condition of shakedown is introduced. Without this theorem the solution becomes useless since the resultant permanent set of plating tends to infinity which causes fracture.
