【摘要】：通过汇总和分析大量国内外相关文献,对纤维增强水泥基复合材料开裂模型的发展进行了综述,并采用实测数据对J积分模型进行了检验。结果表明,J积分法的推论与试验测试结果基本一致,其推荐的两个最小性能指标可为高性能纤维增强水泥基复合材料的设计提供有效的指导。在未来的研究过程中还应再建立一个反映裂缝饱和程度的指标,从而在设计阶段就能对多缝开裂进行全面控制。
[Abstract]:The development of crack model of fiber reinforced cement matrix composites was summarized by summarizing and analyzing a large number of related literatures at home and abroad. The J integral model was tested by the measured data. The results show that the corollary of the J integral method is basically consistent with the test results, and the two minimum performance indexes recommended by this method can provide effective guidance for the design of high performance fiber reinforced cement matrix composites. In the process of future research, a new index reflecting the degree of fracture saturation should be established, so that the multi-joint cracking can be controlled comprehensively in the design stage.
