Influence of the Amount of Steel Fibers on Fracture Energy and Drying Shrinkage of HPFRCC
The fracture energy of the high-performance fiber-reinforced cement-based composite (HPFRCC) can be modified within wide limits by the variation of the amount of steel fibers added to the fresh mix.

Coniform-shape tool for splitting of wooden logs
The article deals with design of a coniform tool with rotary motion for splitting of logs. The tool is proposed using a fracture mechanics theory. The approach of energy balance during crack growth in a split wood log is applied for construction design ...

Wedge splitting test for a steel–concrete interface
Abstract This paper presents a test method designated for the determination of the stress–crack opening relationship of a steel–concrete interface. The method is based on the well known wedge splitting test (WST), and it is illustrated how to obtain the stress–crack opening relationship through an inverse analysis.

Fracture energy evaluation of refractories in wedge splitting tests from notch opening displacements [PDF]
Abstract The work of fracture of refractories is commonly calculated from crack mouth opening displacements (CMODs) in wedge splitting tests (WSTs). This paper proposes a methodology for estimating the fracture energy from notch opening displacement (NOD) measurements, which is useful for setups where CMOD is not accessible.

Combined damaged elasticity and creep modeling of ceramics with wedge splitting tests
Abstract During the crack propagation in common refractory ceramics at high temperatures, creep may occur in the wake of a process zone and in front of a crack tip. To account for this phenomenon, an integrated material constitutive model was developed by combining the mechanical behavior following isotropic damaged elasticity concept and Norton ...

On the calibration of cohesive parameters for refractories from notch opening displacements in wedge splitting tests [PDF]
Abstract Cohesive elements are commonly used to describe crack propagation in heterogeneous materials with toughening mechanisms. This work aims to provide a guideline on how these fracture parameters can be calibrated using notch opening displacements (NODs) measured via digital image correlation and force data from wedge splitting tests (WSTs ...
