Abstract
Varjenje je tehnološki postopek trajnega spajanja materialov, pri katerem se dve ali več komponent združi s pomočjo toplote, pritiska ali kombinacije obeh. Postopek varjenja s trenjem in mešanjem (FSW) spada med varjenja v trdnem stanju in je še posebej primeren za materiale, ki jih je težko variti s klasičnimi postopki. Na podlagi obstoječe literature in predhodnega znanja smo zasnovali posplošen numerični model varjenja, ki temelji na sklopljeni Euler-Lagrangeevi metodi. V programskem okolju Abaqus smo izvedli več termo-mehanskih analiz z različnimi vhodnimi parametri. Pri oblikovanju modela smo uporabili masno skaliranje, kar se je izkazalo za učinkovito pri izboljšanju računskih zmogljivosti. Dobljeni rezultati simulacij so pokazali primerljive vrednosti z že obstoječo literaturo.

Title:Thermo-mechanical analysis of friction stir welding
Abstract:
Welding is a technological process of permanently joining materials, in which two or more components are combined using heat, pressure or a combination of both. The friction stir welding (FSW) process belongs to solid-state welding and is especially suitable for materials that are difficult to weld using conventional methods. Based on existing literature and prior knowledge, we designed a generalized numerical model that is based on the coupled Euler-Lagrange method. We performed several thermo-mechanical analyses with various input parameters in the Abaqus software environment. During the model design, we used mass scaling, which proved to be effective in improving computational performance. The simulation results were comparable to data from existing journals.

Keywords:thermo-mechanical analysis, friction stir welding, coupled Eulerian-Lagrangian method (CEL), finite element method, mass scaling, Abaqus
