DYNAMIC LOADINGS DUE TO WAVES AND SHIP MOTIONS

After consideration of the ways that a ship's hull can fail, a review is first given of the major longitudinal bending loads -- with particular attention to the present status of knowledge of wave bending moments. Correlations are given between predicted trends, using both theory and model tests, and full-scale observations. Vibratory responses, both transient (slamming and whipping) and cyclic (springing), are discussed, as well as loadings resulting from uneven thermal gradients. Finally, consideration is given to ways of improving design load standards on the basis of present knowledge. Further needed research and the future application of reliability theory is discussed.
