Lecture

Extrusion and Wire Drawing: Principles and Applications

Description

This lecture covers the principles and applications of extrusion and wire drawing processes, highlighting the advantages of material economy and the generation of compressive stresses. It explains the differences between direct and indirect extrusion, as well as the extrusion of tubular profiles. The lecture also delves into the geometric and physical relations involved in the extrusion process, emphasizing the specific work of deformation. Additionally, it discusses the wire drawing process, including the drawing and nomenclature aspects. The session concludes with a focus on the specific work of deformation in extrusion and wire drawing, considering the strain rate and real stress. Throughout the lecture, various formulas and diagrams are used to illustrate key concepts.
