heal.abstract	The objective of the present work is the study of aluminum alloy extrusion. Specifically, a specimen of 5052 alloy was used to obtain experimental data, followed by an attempt to create a realistic numerical simulation model for the extrusion process using the LS-DYNA computational software. The first chapter addresses the various types of extrusion processes, the phases involved in the extrusion procedure, the underlying theory, and the parameters influencing the process, such as temperature, surface lubrication, the types of defects that appear in the final product, and finally the equipment and metals that are typically used in this kind of process. The second chapter focuses on the Finite Element Method (F.E.M.), on the types of elements utilized, mesh generation techniques, and the remeshing procedure are categorized and extensively analyzed. The third chapter presents the laboratory equipment, the procedure of the physical extrusion experiment, as well as the calculation of the load and work required during the process. Furthermore, the imperfections observed in the final product are described. The fourth chapter elaborates on the methodology for designing the extrusion model using the LS-PrePost© package, followed by a reference to the numerical simulation of the aluminium specimen's extrusion process conducted via the LS-DYNA solver. In the fifth and final chapter, the experimental data and simulation results are compiled and the derived conclusions are analyzed. At the end, the bibliography referenced for the preparation of this study is presented.	en
