T-STRESS VALUES DURING FRACTURE IN WEDGE SPLITTING TEST GEOMETRIES: A NUMERICAL STUDY

2009
The paper is focused on a detailed numerical analysis of the stress field in specimens used for the wedge splitting test (WST), which is a convenient alternative to the classical bending and tensile tests within the area of determination of the fracture-mechanical parameters of quasi-brittle building materials, particularly cementitious composites.

Testing of fracture mechanical parameters in concrete by means of wedge splitting test

2000
In this work, the new equipment designed in order to determine the fracture mechanical properties of concrete is described and discussed. A special investigation concerning the friction influence during force transfer, COD-measurement unit mounting and fixing and stable crack growth were carried out.

FE-Simulation of the Wedge-Splitting Test on High Strength Concrete (HSC)

1994
In order to determine the fracture energy Gf, several wedge-splitting tests have been carried out on HSC, which should be confirmed numerically. Generally, in FE-simulations of wedge-splitting tests, the applied forces are modelled incompletely. A possibility is described to circumvent this inaccuracy, what results in a better approximation of the ...
