The numerical simulation of the tree pulling test was carried out in the thesis. ANSYS Parametric Design Language was used for the simulation. The parametric design enables use of simulation for variations of tree dimensions, material properties and device positions. Results from numerical solution were compared with a field experiment and analytical solution in cases of three oaks. To found significant influence of input parameters probabilistic analysis was carried out. The analysis found that there is a significant correlation among stem diameter, root volume and tree inclination and nodes displacement on the tree stem. The influence of stem defect and root-plate damage on ability of devices was found as well. Numerical model can be used for the simulation of tree pulling test in wide variety of different configurations, for example change of geometry, material properties and defects extension and position of stem and root-plate system. The practical impact of results and further development of numerical simulation are discussed at the end.
