20.500.12556/DKUM-96816 Experimental and numerical investigation of the deep drawing process using a tractrix die – an industrial case study focused on stress and temperature analysis The deep drawing process of thick sheet metal for vessel production is carried out by applying a tractrix die with the absence of a blank holder, which has economic benefits for industrial production. The main aim of the paper is the development of a reliable numerical thermo-mechanical model of a silicon brass vessel manufactured by a deep drawing process in a tractrix die and a subsequent ironing process, which includes the previous assembly of the dies with reinforcing rings that creates the required prestresses. The testing of the mechanical properties of silicon brass CuZn24Si was carried out by a standard uniaxial tensile test, thus a flow curve was determined to describe the material behaviour. The initial temperatures of the environment, blank and tools were measured with an infrared thermal imager. A comprehensive finite element stress analysis of the deformable tools was carried out for the assembly phase of the dies, and for workpiece and tools in the deep drawing and ironing processes. The comparison of measured and numerically estimated temperatures had a good agreement, so the developed numerical model was confirmed and validated. This research study demonstrates how different process parameters can be investigated through a reliable and precise numerical model with complementary experimental research for the optimization of industrial technology. deep drawing tractrix die reinforcing rings finite element method FEM experimental-numerical approach numerical modelling simulation infrared imaging technology simufact.forming globoko vlečenje numerično modeliranje metoda končnih elementov true false true Chair of Production Engineering (CPE), University of Maribor Faculty of Mechanical Engineering Angleški jezik Slovenski jezik https://apem-journal.org/ Članek v reviji 2026-01-29 08:01:17 2026-01-29 08:01:18 2026-01-30 03:12:03 0000-00-00 00:00:00 2024 0 0 str. 133-148 no. 1 Vol. 19 March 2024 0000-00-00 Zaloznikova Objavljeno NiDoloceno 2023-12-28 2024-03-01 2024-04-29 658.562 266558979 10.14743/apem2024.1.498 1854-6250 APEM19-1_133-148.pdf APEM19-1_133-148.pdf 1 6C07C805EC6438ACEBDF032438EC0B23 fc84ea8d85d22e37e96c0465b72cc1c00bdca6a9fd248547c4d4061ec4b81ab9 caad3ceb-fce0-11f0-a012-00155d00018d https://dk.um.si/Dokument.php?lang=slv&id=202746 https://apem-journal.org/Archives/2024/Abstract-APEM19-1_133-148.html 0 d1673dd8-fce0-11f0-a012-00155d00018d https://dk.um.si/Dokument.php?lang=slv&id=202747 Fakulteta za strojništvo Advances in production engineering & management 0 0 0
