混凝土异弹模界面裂缝断裂准则的试验研究
Experimental investigation on fracture criterion for niterface crack of concrete with different elastic properties
【摘要】 对四点加荷试件进行了混凝土导弹模界面裂缝沿非交界面扩展时断裂准则的试验研究,得到了这一问题的临界断裂曲线,并研究了最大拉应力准则及最大拉应变准则在异弹模界面裂缝中的应用问题.
【Abstract】 This paper presents the experimental investigation on the fracture criterion for interface crack of concrete with different elastic properties by using four point loading specimens.The characteristic curve of critical fracture is obtained. The application of the maximum tensile stress and maximum strain criterions to predict the interface crack of dissimilar materials are disscussed.
