混凝土、纤维混凝土的Ⅰ型断裂

MODE Ⅰ FRACTURE OF CONCRETE OR FRC

  • 摘要: 本文论述求混凝土、纤维混凝土试件在小于断裂荷载的外力作用下,裂纹的非线性扩展及如何用它来确定材料的断裂韧度。另介绍了作者提出的纤维混凝土的一般拉伸软化曲线及分析裂纹构件最大断裂荷载的有关方法。

     

    Abstract: In this paper the nonlinear slow crack growth occurring prior to the peak load for concrete or F. R. C. notched specimens is discussed. A standard softening curve for FRC in opening mode is proposed and its usage in predicating fracture peak load is introduced.
