description: The subject of this degree qualification paper is âModelling of core deformation processes with reference to reconstruction of pore-volumeâ. The main goal of this work is to study usage of digital twin, which was derived from X-Ray tomography images of heterogeneous pore-volume structure, to determine physical and mechanical properties. In the course of this work following problems were solved: 1. Analysis of basic core datum and methodology of petrophysical studies; 2. Research on basic methods of pore-volume structure determination;3. Development of program âReconstructerâ, which will create finite element model of core; 4. Determination of basic physical and mechanical properties of core model setting experiments in view of both elastic and elastic-plastic theories; 5. Analyze the impact of porosity on physical and mechanical properties. During the study X-Ray tomography images were analyzed, using them different elementary finite element models were created. We have created program and methodology for reconstruction and analysis of pore-volume structure. The model calculations have been performed in ANSYS finite element analysis software in various settings of loading to determine both elastic and elastic-plastic properties of material. Derived stress-strain curves were analysed as same as the impact of porosity on physical and mechanical properties of core.
