Fatigue crack behaviour: comparing three-point bend test and wedge splitting test data on vibrated concrete using Paris' law [PDF]
Fracture and Structural Integrity, 2017 The fatigue behaviour of concrete has become more important for the design of constructions due to the desire to build slimmer structures, which are more sensitive to fatigue loading.

Wedge-Splitting Test on Carbon-Containing Refractories at High Temperatures [PDF]
Applied Sciences, 2019 The mode I fracture behavior of ordinary refractory materials is usually tested with the wedge-splitting test. At elevated temperatures, the optical displacement measurement is difficult because of the convection in the furnace and possible reactions of ...

Wedge Splitting Test: Displacement Field Analysis by Multi-parameter Fracture Mechanics [PDF]
Transactions of the VŠB – Technical University of Ostrava, Civil Engineering Series, 2019 Multi-parameter fracture mechanics is nowadays quite extensively applied when cracked structures/specimens are investigated. The reason was that it has been shown that it can be helpful and bring results that are more accurate when for describing of ...

Numerical study and pilot evaluation of experimental data measured on specimen loaded by bending and wedge splitting forces [PDF]
Fracture and Structural Integrity, 2017 The fracture mechanical properties of silicate based materials are determined from various fracture mechanicals tests, e.g. three- or four- point bending test, wedge splitting test, modified compact tension test etc.

A modified wedge splitting test for susceptible quasi-brittle materials
Construction and Building Materials, 2021 A modified version of the wedge splitting test is proposed, aiming at the investigation of susceptible materials like young, hydrating concrete and shotcrete. Compared to the classical test, the employed specimens do not require a groove for mounting the wedge splitting device.

Multi-parameter crack tip stress state description for estimation of fracture process zone extent in silicate composite WST specimens [PDF]
Fracture and Structural Integrity, 2013 For wedge splitting test specimens, the stress and displacement fields both in the vicinity and also in larger distance from the crack tip are investigated by means of numerical methods. Several variants of boundary conditions were modeled.
