標題: | Crack-wake interfacial debonding criteria for fiber-reinforced ceramic composites | 作者: | CHUN-HWAY HSUEH | 公開日期: | 1996 | 卷: | 44 | 期: | 6 | 起(迄)頁: | 2211-2216 | 來源出版物: | Acta Materialia | 摘要: | The condition for progressive debonding with friction along the debonded interface is considered for the bridging fiber in the crack-wake of fiber-reinforced ceramic composites. The energy-based criterion is adopted in the present study to analyze the debond length, the crack-opening displacement, and the displacement of the composite due to interfacial debonding. The results are identical to the previous results obtained from a simple approach, in which interfacial debonding is assumed to occur when the mismatch in the axial strain between the fiber and the matrix reaches a critical value. Furthermore, the mismatch-strain criterion is found to bear the same physical meaning as the strength-based criterion. |
