Abstract : This report describes a statistical methodology that forms a key part of an interdisciplinary approach to damage prediction. The principal problem addressed is that of predicting submarine hull rupture caused by an underwater explosion. The statistical approach is compared with two other current approaches to the problem. The statistical approach is shown to be a synthesis and extension of these more deterministic alternatives. The report discusses the role of deterministic physical models in response prediction and how powerful deterministic computer codes can be utilized in constructing probability models for dependent, multivariate damage responses of interest. It describes how the statistical approach provides an essential framework within which issues such as prediction accuracy, model validation, and decision making can be qualitatively and objectively addressed.
