加勁板由於具有較大的勁度／重量比，因此廣泛的應用於船舶、車輛、航空器等載具結構上，以強化板列結構承受荷載的能力。因此，本計畫利用有限單元分析程式ABAQUS，進行網格加勁板（grid stiffener plate）承受衝擊作用的動態反應之研究，分析平板、單向加勁板、網格加勁板之抗震能力，並研究加強肋的型式對結構承受衝擊的影響。

Owing to the stiffener plates subjected to static, periodic or random loads are commonly used in the structures of ship, vehicle and airplane. Basing on the nonlinear finite element code ABAQUS, this investigation focus in the problem of dynamic responses of a grid stiffened plates subjected to an impulse. This study presents the effects of vibration resistance between normal plate, unidirectional stiffened plate and grid stiffened plate. Besides, we investigate the effects of the dimensions and types of stiffener to plate under impulse. The study attempts to supply a reasonable comprehensive account, which will be used in designing ship hulls so as to enhance resistance to impulse wave. In addition to, these results could be the matters for tuition in marine engineering department of the maritime technology
