本研究針對具曲度及變剖面微觀構件之蜂巢材料,探討此二類微構件缺陷對蜂巢材料彈性模數、柏松比和塑性降伏強度之影響,首先,建立一具曲度及變剖面蜂巢材料之幾何模型,再利用材料力學方法於曲度及變剖面之微構件缺陷條件下,應用樑之變形理論推導其彈性變形,進而獲得具曲度與變剖面蜂巢材料之彈性模數、柏松比和塑性降伏強度,發現此類蜂巢材料之力學行為與其微觀結構息息相關,由推導結果發現其彈性模數與塑性降伏強度之變化趨勢類似。另外,應用數值結果建立此蜂巢材料力學性質與相對密度之關係式,再利用回歸方法獲得與其他微觀參數之關係式,故由所求得關係式可準確預估其彈性模數與塑性降伏強度,更進一步可利用本研究所得之關係式,設計或改良於不同微觀參數下之蜂巢材料,對不同工程設計需求下可尋獲一具最佳微結構之蜂巢材料。
