NUMERICAL ANALYSIS OF MATERIAL STRAIN AND FORCES IN THE PROCESS OF INDIRECT EXTRUSION OF THIN-WALLED TUBE ITEMS

摘要

This paper presents a numerical analysis of the state of strain of material in thin-walled tube items, indirectly extruded with various levels of strain. FEM calculations were performed for soft aluminium using Deform 2D program. Analysis of values and courses of the extrusion force were made as well.
