FINITE ELEMENT PREDICTION OF MEASURED BOW FLARE PLATE STRESSES UNDER DYNAMIC WAVE LOADING

Finite element predictions of plate bending stresses in the bow flare of the research vessel CFAV QUEST are compared to measured strain data from dynamic wave pressure loading. The pressure loading time history data used in the finite element analysis were derived from transducers mounted flush in the bow shell plating. Results are also compared to a static clamped plate design formula. The effects of dynamic behavior and unsymmetrical and uncertain plate boundaries are shown to be significant. This information will aid in assessing the applicability of simplified design formulae for ship hull plating. The ultimate goal, of which this study is a part, is to relate ship structural response to sea state, an important step in developing rationally-based design methods. The finite element predictions were in good agreement with the measured data, indicating that the finite element method is a suitable--although somewhat complex--method of deriving expected response from specified expected pressure loading.
