Determinación de la ley de endurecimiento del cobre electrolítico procesado mediante trefilado

Abstract

 In the industrial process of multi-stage sequential drawing, 
the previously annealed wire is passed through a series of 
rows arranged consecutively by means of a traction system, 
progressively reducing its section while its length increases, 
causing the metal to harden.
In the present work a complete study of the material has been 
made, before and during the multi-stage wiredrawing process, 
to know the evolution of its main mechanical properties when 
being processed by drawing in successive stages.
The results obtained have allowed to establish a hardening law 
with great utility to predict the plastic behaviour of this metal 
when it is transformed by this process.
The study has been completed with a series of FEM simulations 
performed on the Finite element method (FEM) analysis which 
have allowed to implement the behaviour law established from 
the experimental work and analyze the sequential process by 
numerical method.
