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

A modified wedge splitting test for susceptible quasi-brittle materials
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.

Numerical Simulations of a Wedge Splitting Test for High-strength Concrete
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.

Wedge splitting test of wood for fracture parameters estimation of Norway Spruce
Abstract Crack evolution in wood from Norway Spruce during mode I wedge splitting tests was measured using a Digital Image Correlation (DIC) system. The resulting series of deformation fields were post-processed in order to obtain kinematically based crack tip location histories throughout the loading procedure, by a purposely made algorithm.

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

Analysis of wedge splitting test on refractory castable via integrated DIC [PDF]
One of the key mechanical properties of refractories is their toughness. The latter can be evaluated via wedge splitting tests. One such test is analyzed herein with an integrated approach to digital image correlation. The position of the crack tip, stress intensity factors and T-stress are estimated on two faces of the tested sample made of a ...

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