摘要: 本文,对混凝土弯曲试样进行了测试,并用四种不同的方法进行了平面应变断裂韧性的计算和比较。混凝土具有粘弹性质,应用流变理论较为适宜。

Abstract: In this paper, the test results of bending concrete specimens are shown, and the values of plane-strain fracture toughness, calculated by four different methods, are compared with one another. Owing to the viscoelasticity behavior of concrete, it is better to use the theory of rheology.
