Correlation between tension softening relation and crack extension resistance in concrete

Xiufang ZHANG , Shilang XU ,

Frontiers of Structural and Civil Engineering 2009, Volume 3, Issue 3,   Pages 323-329 doi: 10.1007/s11709-009-0041-2

Abstract: Changes of the material fracture energy consumption with crack propagation can be described by a crackextension resistance curve, one of the fundamental fracture criteria in crack mechanics.Recently, experimental observation of the fracture behavior in concrete was used to develop a new fracturecriterion, the crack extension resistance curve, to analyze crack propagation during the entire concretefracture process zone ahead of the stress-free crack tip.
