摘要
混凝土的拉伸破坏机理比较复杂,尚无合适或简便的力学模型和研究方法。借鉴复合材料力学分析方法,采用一种有限子层剪滞模型,并结合线弹性断裂力学,来分析含裂缝混凝土试样的拉伸破坏问题,可为混凝土的破坏分析提供一种新的研究方法。
The mechanism of tensile failure of concrete is rather complex, so there are no suitable or convenient mechanics models and research methods. By learning the analysis method of composite material mechanics, using a kind of limited sub-sheaf share lag model and combining with linear elastic fracture mechanics to analyze the tensile failure of concrete samples with cracks provides a new research method for the analysis of concrete destruction.
