摘要
本文介绍一些研究者关于砼Ⅱ类断裂的试验结果,并从能量平衡角度进一步解释了砼Ⅰ、Ⅱ类断裂现象。本文还探讨了通过数值方法来模拟砼Ⅱ类断裂,进而采用数值手段分析了随一些因素变化砼Ⅰ、Ⅱ类断裂的转化。
This paper presents the results of Class Ⅰ, Ⅱ fracture mode of concrete tested by some researchers. Based on energy equilibrium, this paper discusses the phenomena of Class Ⅰ, Ⅱ fracture mode,and emphasizes numerical analysis of Class Ⅱ fracture mode. With the numerical method. A transformation between Class Ⅰ and Calss Ⅱ fracture mode with some factors is analysed by the numerical method.
