Comparison Between Numerical Analysis and Actual Results for a Pull-Out Test

Jakub GONTARZ, Jerzy PODGÓRSKI, Józef JONAK, Marek KALITA & Michał SIEGMUND
The paper describes a computer analysis of the pull-out test used to determine the force needed to pull out a fragment of rock and the shape of this broken fragment. The analyzed material is sandstone and porphyry. The analysis included a comparison of different methods of propagation of cracks in the Abaqus computer program using the Finite Element Method. The work also contains a description of laboratory tests and analytical considerations.

Porous volumetric structures obtained by additive manufacturing technologies

Kamil Kaszyca, Wojciech Danilczuk & Rafał Zybała
The goal of our work was to develop bulk structures characterized by a variable, controlled porosity, using additive manufacturing techniques (3D printing). A technology for the fabrication of bulk materials with controllable porosity has been developed. For that purpose, the samples with constant porosity were designed and then prepared, which allowed us to learn the possible limit values. Thus, we were able to optimize the design process at the stage of the preparation of the...
