摘要
本文试图应用初等突变理论,分析混凝土的稳定与不稳定断裂、延性与脆性断裂的关联.文中建立了混凝土尖点突变断裂模型.并据此方便解释了混凝土的猝断现象及裂缝的突发然展.
This paper discusses the research of concrete fracture and the methodological basis of the catastrophe theory.The cusp catastrophe model of concrete fracture was thus advanced.On the basis of the model,the appearance of concrete abrupt fracture and the sudden propagation of the crack is adeguately explained.The quantitative analysis of facture mechanism,the further researches into the construct of micro-model as well as the forecast and control of fracture are thereafter made possible
