- This work shows a case study into 3D modelling, numerical simulations, and preliminary research of self-designed test rig dedicated for uniaxial tensile testing using pillar press. Innovative device was CAD modelled, FEM optimized, build-up according to the technological documentations. Then, the device utilization for tensile testing was validated via preliminary research. 3D model of the device was designed and FEM-analyzed using Solid Edge 2020 software. The set of FEM simulations for device components made ofstructuralsteel and stainless steel and at a workload equal 20 kN were conducted. This made it possible to optimize dimensions and selection of material used for individual parts of the device structure. Elaborated technical documentation allows for a buildup of a device prototype which was fixed into the pillar press. After that, the comparative preliminary experiments regarding tensile strength tests of X5CrNi18-10 (AISI 304) specimens were carried out. Tests were done using the commercial tensile strength machine and obtained results were compared with those received from an invented device. The ultimate tensile strength of X5CrNi18-10 steel, estimated using the commercial device (634 MPa) and results obtained from the patented device (620 MPa), were in the range of the standardized values. Findings confirm the utilization of the invented device for tensile strength testing.
