In this master thesis we deal with the stress-strain states that occur between a steel roller and a steel strip supported by an aluminium alloy profile. To determine the stress-strain states, numerical analyses were carried out using the finite element method. In the theoretical part, the mechanical properties of the used materials and the challenges of their combined use are presented, followed by Hertzian contact theory and the determination of the static load capacity of rolling elements according to the SIST ISO 14728-2:2020 standard. In the methodology chapter, the assumptions and the process of creating the numerical models are presented. The results include a presentation of the stress-strain states of the individual iterations of the structural optimization and considerations of the effects of design changes on load capacity. Finally, the conclusions summarize the results and findings and contain suggestions for further work.
