Numerical modelling of ODS steel tube cold pilgered by HPTR. Focus on experimental measurements and simulation of residual stress.

Abstract : Oxides Dispersed strengthened (ODS) stainless steels are foreseen for fuel cladding tubes in the coming generation of fission sodium cooled nuclear reactors. Classically those steels are cold formed as cladding tubes by a sequence of milling passes with intermediate heat treatments. This study focuses on numerical simulation of tube cold pilgering by High Precision Tube Rolling (HPTR). A 3D Finite Element Method mechanical analysis of the HPTR process is proposed. Results are confronted to experiments regarding geometry and residual stress.
