Numerical Simulations of a Wedge Splitting Test for High-strength Concrete
Procedia Engineering, 2014 AbstractThe paper presents results of wedge splitting tests (WST) for high-strength concrete performed in a laboratory and an attempt to develop a numerical model of the test. Characteristics of high-strength concretes as well as the experimental setup of WST are presented.

Determining fracture energy parameters of concrete from the modified compact tension test [PDF]
Fracture and Structural Integrity, 2014 The modified compact tension (MCT) test, though not yet recognized as a valid test for determining fracture energy of concrete, is believed to represent a plausible and suitable alternative versus other well established procedures, such as the wedge ...

Fracture energy evaluation of refractories in wedge splitting tests from notch opening displacements [PDF]
Journal of the European Ceramic Society, 2021 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.

A projection-based approach to extend digital volume correlation for 4D spacetime measurements
Comptes Rendus. Mécanique, 2023 In-situ (tomography) experiments are generally based on scans reconstructed from a large number of projections acquired under constant deformation of samples. Standard digital volume correlation (DVC) methods are based on a limited number of scans due to

Some Remarks on the Use of Deterministic and Probabilistic Approaches in the Evaluation of Rock Slope Stability [PDF]
, 2020 The rock slope stability assessment can be performed by means of deterministic and probabilistic approaches. As the deterministic analysis needs only representative values (generally, the mean value) for each physical and geo-mechanical parameter ...

Vibrated concrete vs. self-compacting concrete: comparison of fracture mechanics properties [PDF]
, 2014 This study focuses on the fracture mechanics aspect of self-compacting concrete, compared to vibrated concrete. The most commonly used experiments to investigate the toughness and cracking behaviour of concrete are the three-point bending test (3PBT) on ...

Influence of the Amount of Steel Fibers on Fracture Energy and Drying Shrinkage of HPFRCC
Advances in Materials Science and Engineering, 2020 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.
