Abstract
The paper presents results of 3D numerical modeling and calculations of a plain bar Ø16 mm concreted in the concrete cube during pull-out test. The prepared geometry reflected real sample dimensions. The mechanical parameters of the materials and assumptions for analysis were adopted based on the results obtained from the experimental tests previously carried out. Numerical calculations included non-linear finite element method (FEM) analysis. As a result of numerical calculations, it was possible to trace the deformation state, stresses and cracking as well as their development along with the change of the bar displacement in the sample. The increase of strains and stresses into the concrete sample occurred until the maximum value of the concrete-steel bond in accordance with the bond model was achieved. After exceeding the top, there was a constant decrease in strains and stresses in concrete with the increase in displacement of the bar (with extension). The first cracks appeared at a slip of approximately 0.1 mm. Cracking of concrete progresses with the increase of the bar displacement in relation to the concrete.
