Spatial Modeling of Wedge-Splitting Test on Cylindrical Specimens Using FEM Software

This paper discusses numerical models of the wedge-splitting test on cylindrical specimens made of quasi-brittle material. These models are used for predictions of crack/damage propagation and are crucial for the further evaluation of fracture parameters. Validation of these models is made based on experimentally obtained data. To assemble the numerical models, ATENA FEM software was used. In this software, damaging of the structure/specimen caused by cracks, their initiation and progressive propagation throughout the loading process, can be modelled. In this case, the material model for concrete based on cohesive crack approach was used. The analysis is focused on comparison of the 2D and 3D numerical models created with real material properties obtained from experimental data.
