三明治蜂窩結構為複合材料結構，因其具有質量輕盈、良好緩衝吸能、高強度、用料節省等的優點，被廣泛應用至航太、軍事等結構。而在軍事應用上，蜂窩結構將有效提高結構對外力衝擊上之抗衝擊性及防爆性能，而在爆炸荷載後，也需評估結構構件在爆炸荷載下產生之損傷破壞。
本文針對受爆炸荷載下之三明治蜂窩板，依序介紹修正後之理論公式，並使用有限元素軟體ABAQUS，進行模擬分析，與理論公式及實驗數據對比，具有一致性，並透過底板中心位移及能量歷時探討其動態響應，以及透過不同幾何參數的考量，描述對結構的影響，最後以結構受爆炸荷載後之剩餘承載力為損傷破壞指標，經過大量的數值計算，得出壓力-衝量曲線(P-I curve)，可象徵不同壓力、衝量荷載下，三明治蜂窩板之損傷程度。
三明治蜂窩板需考慮脫層因素，若面板與芯材間發生脫層，誤差在位移上可達30~40%，而在幾何參數之考量，調整面板厚度及芯材壁厚，以改動面板厚度質量性能比較佳。受爆炸荷載後之三明治蜂窩板，可由剩餘承載力作為良好的損傷破壞指標，並且由擬合公式可以快速的繪製P-I曲線，在數點數值驗證上其依靠擬合公式得出之結果十分可靠。

Honeycomb sandwich structure is widely used in aerospace and military engineering due to its quality of light, good energy absorption… etc. Also, be used in military engineering, it can efficiently improve the resistance against blast loading. After blast impulse, we need to measure the damage that occurred during the explosion.
The thesis focuses on the honeycomb sandwich panel that has been through the explosion impact. It introduces modified theoretical formula, and uses finite element analysis software ABAQUS to operate the simulate analysis. The report shows that the results of two different methods match each other. Also, by observing the displacement of bottom plate center point and energy-time diagram, we are able to discuss its dynamic response. There will be different results by changing geometric parameter. At last, we can determine the damage index which relies on the residual bearing force subjected to blast loading. Through a large amount of numerical simulation, we can get Pressure-Impulse (P-I) curve, which indicates the damage assessment of honeycomb sandwich panel under varying pressure and impact.
Delamination is considered as an important issue for honeycomb sandwich panel under blast loading. If there is delamination between plates and core, the error of displacement can be up to 30 to 40%. Taking geometric parameter as consideration, varying plate thickness gives better effect than varying cell thickness. Residual bearing force becomes a good damage index for honeycomb sandwich panel subjected to blast loading. We can use fitting formula to efficiently create a P-I curve, and the result is reliable which is proven by simulation.
