纤维束复合材料在剪力作用下的力学性能

The Effective Properties of Fiber-Bundle Reinforced Composites Under Shear Loading

利用细观力学模型研究在剪力作用下复合材料的性质 .以单纤维复合材料为基础 ,利用平面应变模型和有限元法计算了 3根束和 4根束纤维增强复合材料的弹塑性应力—应变关系 .

In present research, the effective properties of the composites for the pure shear case will be investigated. Based on the micromechanical model of single_fiber composites, the work is extended to composites reinforced by fiber bundles. The plane strain models for 3_fiber bundle and 4_fiber bundle composites are studied. The effective elasto_plastic properties are predicted numerically for boron/aluminum composites.
