Abstract. This paper compares the external expansion of a thick-walled test
cylinder manufactured from EN1A free-cutting, mild steel, when subjected to
an internal pressure with that of a simulated autofrettaged thick-walled
cylinder cross-section, using finite element (FE) analysis. The results produced
by FE are also compared with the conventional approach used
for evaluating external strain in a thick-walled cylinder. This paper
assumes kinematic material hardening (bilinear and multilinear) characteristics with Bauschinger
effect. Comparison of results shows that those results produced by
FE analysis are in good agreement with experimental results. The
paper also highlights the appearance of Luder's band (stretch marks)
on a thick-walled cylinder, due to plastic yielding.
