THEORIES AND TECHNIQUES FROM STRENGTH OF MATERIALS WITH RESPECT TO SHIP DESIGN AND CONSTRUCTION

The notes that follow attempt to show a practical application to ship design and construction of the topics covered in the ME ^>2i and ME 522 course sequence. ' A large number of references have been included simply to acquaint the reader with some of the more readily available publications * A lot of material has been covered * The inadequacy of discussion will be obvious, but hopefully may arouse some curiosity* A large amount of time will be allotted to beam theory in the courses mentioned * Take this as a point of departure and see where the beam theory, as applied to ship structure, will lead* Ships are hollow structures that carry different things to different places for different reasons * The external shape, as defined by the moulded lines, is determined by factors such as purpose of ship, desired capacity and powering, with no regard to strength * 1 The resulting hull, when structurally assembled, can be looked at as a flexible hollow box girder (beam) supported by a varying elastic support, the water* Figure 1 describes the shape of a typical merchant x ship hull * The three views noted are actually represented to scale on a "lines drawing*, an example of which is shown in Figure 2* 1 Numbers in superscript position refer to references listed at end of notes* (i) tt^ZBtoST
