A Study of Ship Hull Crack Arrester Systems.
Abstract
A world-wide survey of marine engineers, shipyards, and regulating agencies was conducted to ascertain both current and contemplated approaches to arresting cracks in ship hulls. A crack arrester classification system was developed and used to aid in a systematic investigation aimed at determining the most attractive practical schemes for arresting cracks in ship hulls. In addition to describing the classification system, example calculations showing quantitatively the effect of imposing various kinds of mechanical arrester devices in the path of a fast-moving crack are given. Considerable background material on the theoretical concepts and material characterizations required for the arrest of fast fractures and fatigue is also given. Taken together, the work described in the report can be used as a first step in developing guidelines for ship designers in situations where structural perturbations for the purpose of arresting unstable crack propagation are envisioned.
