Numerical Simulations of a Wedge Splitting Test for High-strength Concrete [PDF]

open access: yesProcedia 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.

A modified wedge splitting test for susceptible quasi-brittle materials

open access: yesConstruction 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.

Wedge-Splitting Test on Carbon-Containing Refractories at High Temperatures [PDF]

open access: yesApplied 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 ...

Semi-analytical solution of cohesive zone model for cement-based materials [PDF]

open access: yesScientific Reports
The low tensile strength characteristics of cement-based materials are the biggest defect restricting their use. Understanding the mechanisms behind tensile cracking shows great significance in guiding the design of cement-based materials and their ...

Analysis of a castable refractory using the wedge splitting test and cohesive zone model

open access: yesJournal of the European Ceramic Society, 2019
Abstract A cohesive zone approach is applied to the wedge splitting test (WST) using the finite element code Abaqus to obtain the tensile strength, the fracture energy and insight about the crack wake region. A finite element model updating (FEMU) method, with a cost function based on the measured load (FEMU-F), is used to calibrate the sought ...

Wedge splitting test method: quantification of influence of glued marble plates by two-parameter fracture mechanics [PDF]

open access: yesFracture and Structural Integrity, 2014
In the present paper, the well-known wedge splitting test (WST) is applied on specimens with different geometries (S= 150, 200, 300 mm) and variants of the specimens’ configurations.

Numerical study and pilot evaluation of experimental data measured on specimen loaded by bending and wedge splitting forces [PDF]

open access: yesFracture 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.

Evaluation of the Resistance to Crack Propagation of High-Performance Concretes by the Wedge Splitting Test Method

open access: yesAGG+, 2022
This paper describes the key elements of the results of investigations on the resistance to crack propagation carried out as part of a large-scale project to develop high-performance concretes (HPCs) for the secondary lining of a low and intermediate ...

Fatigue crack behaviour: comparing three-point bend test and wedge splitting test data on vibrated concrete using Paris' law [PDF]

open access: yesFracture 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.

Multi-parameter crack tip stress state description for estimation of fracture process zone extent in silicate composite WST specimens [PDF]

open access: yesFracture 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.
