This paper is an attempt to present a methodology for predicting rationally the magnitude of the severe dynamic loads acting on advanced high speed hulls as a result of wave impacts. Having accomplished this the next step is to use this information as input to, say, NASTRAN finite element structural models to investigate the dynamic response of the overall hull to the transient impact forces as well as the local response of the hull plating to the corresponding high impact pressures. Included are the effects of displacement, speed, heading, operational mode (hullborne or cushionborne as in the case of SES'S and ACV'S) and operational environment (wave height and period). Thus, based on experimental observations adequate statistical distributions such as Rayleigh, Weibull, Generalized Gamma, etc. are used to describe the statistics of the loads and their combination so that rational structural design criteria can be developed.
