Influence of fracture process zone height on fracture energy of concrete

Cement and Concrete Research, 2004
Abstract The implication of modelling concrete fracture with a fictitious crack of zero fracture process zone (FPZ) height is addressed because FPZ height, in reality, is not zero and is bound to vary during crack growth. The ligament effect on fracture energy G F is explained by the nonuniform distribution of a local fracture energy g f ...

Fracture Process Zone of Concrete

Journal of Engineering Mechanics, 1985
Double displacement compliance and replica techniques were used to determine the macro and total crack lengths, respectively in nineteen crack-line wedge-loaded, double cantilever beam (CLWLDCB) mode I concrete specimens. Details of the fracture process zone, which lies between the macro and hairline crack tips, were determined through numerical ...

Fracture energy and fracture process zone

Materials and Structures, 1992
The fracture energy Gf can be determined following a RILEM recommendation. However, it has been found that fracture energy depends on both size and geometry of the test specimen. The underlying fictitious crack model postulates that fracture energy, tensile strength, the critical opening of the fictitious crack, and the shape of the softening curve ...

Fracture process zone in granite: a microstructural analysis

International Journal of Earth Sciences, 2001
Shear fracture propagation in rock is accompanied by localized microcracking in a process zone surrounding the fracture tip. We investigated the crack microstructures along experimentally formed shear fractures from four granite samples (uniaxial compression tests).

Development of fracture process zones in concrete

Magazine of Concrete Research, 1990
Concrete specimens have been tested in uniaxial tension using a closed loop servo-controlled testing machine. The combination of extension control and stiff testing frame has allowed stable failure to be achieved and the full post-peak portion of the load/extension relationship to be obtained.

On the role of the process zone in dynamic fracture

Journal of the Mechanics and Physics of Solids, 1996
The evolution of the fracture process zone and its influence on dynamic crack propagation are investigated using a simple constitutive assumption to model the material in the fracture process zone. The mode III problem of anti-plane shear is examined using a finite difference scheme to obtain the full field solution.
