带裂缝混凝土材料力学分析的一种新方法

New Method of Mechanical Analysis on Concrete with Crack

带裂缝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。结合线弹性断裂力学性能,借鉴复合材料力学分析方法,建立一种有限子层剪滞模型,对于带裂缝混凝土试样受拉伸的破坏问题不失为一种有效的分析方法。

Tensile damage mechanism of concrete mechanical model and research method up to now mechanical analysis method of composite material, crack Based complicated, and there are no proper on linear elastic fracture mechanics and a finite sub-layer shear-lay model is established, which is an effective one in solving the problem of tensile damage of concrete with crack.
