摘要

本研究主要探討蜂巢材料承受雙軸壓應力作用下，其微構件剖面對蜂巢材料雙軸破壞面之影響。當一蜂巢材料承受雙軸壓應力作用時，其可能破壞機制包括：彈性挫曲、塑性降伏及脆性破裂等，同時考慮上述破壞機制時，可進一步獲得蜂巢材料之雙軸破壞面。利用有限元素套裝軟體ABAQUS，建立具變剖面微構件蜂巢材料之最小重複單元體分析模式，求得蜂巢材料承受單軸壓應力作用時之彈性模數、彈性挫曲強度及塑性強度，並同時建立無限域蜂巢材料分析模式，求得彈性蜂巢材料承受雙軸壓應力作用時之彈性挫曲強度。另外，利用偉布統計，分析脆性蜂巢材料受雙軸壓應力作用時之脆性破裂強度。最後，利用本文所獲得之彈性挫曲強度、塑性降伏強度及脆性破裂強度，建立具變剖面微構件蜂巢材料承受雙軸作用時之破壞包絡面。
