摘要
介绍了纤维增强水泥基复合材料(FRCC)取得应变硬化行为的微观力学模型,在该模型指导下,综述与分析了纤维类型、强度、长度、直径、体积掺量及纤维表面处理等因素变化对FRCC应变硬化能力的影响。研究成果表明,纤维优化能够稳定取得应变硬化行为或得到更大的应变硬化能力。
The micromechanics models, which provide an opportunity to obtain strain-hardening behavior in fiber reinforced cementitious composites (FRCC), are introduced, and the effect of the fluctuation of fiber type, strength, length, diameter, volume content and fiber surface treatment on the properties of strain-hardening based on micromechanics models is summarized and analyzed. The research results indicate that the fiber optimization can improve the robustness of strain-hardening and achieve better capacity of strain-hardening.
