Sb. Petersen et al., PRODUCTION OF TUBULAR COMPONENTS BY RADIAL EXTRUSION - A FINITE-ELEMENT ANALYSIS, Journal of materials processing technology, 45(1-4), 1994, pp. 87-92
Recent experimental work on radial extrusion of tubular components pre
sents new results relevant to the process and die design. This paper p
resents a comprehensive analysis of the process using the finite eleme
nt method. Results show good agreement with metal experiments namely i
n what concerns the prediction of the material flow as a function of t
he major process parameters. The performed analysis enabled the author
s to design of a two step radial extrusion technique predicted to allo
w an extension of the formability limits for the production of tubular
components. Preliminary tests in aluminum confirm the advantage of us
ing this technique.
