本文針對具曲度及變剖面微構件之脆性蜂巢材料，探討此二類微結構缺陷對脆性蜂巢材料強度之影響。首先，建立一具曲度及變剖面微構件之幾何模型，再利用材料力學方法，藉由樑理論推導，獲得於單軸壓力作用下，具曲度及變剖面微構件蜂巢材料之抗壓強度。此外，考慮脆性蜂巢材料含微裂紋，將導致其強度產生離散性，於是乃利用“偉布分析”獲得脆性蜂巢材料不同破壞機率下之抗壓強度，並探討材質及微構件尺寸對脆性蜂巢材料抗壓強度之影響。最後，考慮脆性蜂巢材料於雙軸壓力作用下之破壞行為，並建立脆性蜂巢材料之雙軸破壞包絡面。

The analysis for the strength of brittle honeycombs with curved edges and Plateau borders is presented here. By using the classical Beam Theory, the strength of brittle honeycombs with dual microstructural defects under uniaxial loading are thus theoretically obtained. The variability of cell-edge modulus of rupture is taken into account in analyzing the strength of brittle honeycombs with dual microstructural defects by using a Weibull statistical analysis. Consequently, the effects of Weibull modulus and cell size are discussed. Also, the failure envelopes caused by brittle fracture for brittle honeycombs with dual microstructural defects under biaxial compressions are developed.
