纤维增强脆性基复合材料界面脱粘过程的数值模拟

Simulation of Interface Debonding Progress of the Brittle Composite Matrix Reinforced by Fiber

研究了纤维增强脆性基复合材料界面脱粘过程中剪应力的变化规律。采用基于细观损伤力学基础上开发的针对材料破坏过程的数值模拟程序,考虑材料物理力学参数在细观尺度上的非均匀性,对界面脱粘过程进行了模拟。结果表明,材料的非均匀性条件对界面脱粘过程有很大的影响。

The interfacial shear stress of a brittle composite matrix that reinforced with fibers is studied. Based on meso-damage mechanical, a numerical program is adopted to simulate the whole process of the debonding. Hetero-geneity is applied to each mechanical parameter. From the simulation, it can be concluded that the heterogeneity greatly influents the progress of the interfacial debonding.
