RELIABILITY AND DAMAGE OF SHIP STRUCTURES

Three aspects of ship reliability are discussed. The first is the buckling collapse of deck plates with distributed initial distortion. At ultimate load, a hinge line forms across a deck following previous successive collapses of weaker panels under extreme wave loads. The second aspect is fatigue damage. A mathematical model is assumed in which the uncertainty of crack initiation in a group of similar structural members is given as a function of time and in which initial crack length is constant. The design criterion for fatigue stress is also discussed. The third aspect is corrosive damage. Theoretical calculations of such damage in ships of several ages and types are compared with observations obtained from survey reports of ships registered with Nippon Kaiji Kyokai.
