3D coupled thermo-mechanical FE modelling and simulation of radial-axial ring rolling

摘要

Radial-axial ring rolling is an advanced plastic forming technique which is used to manufacturenlarge scale seamless rings. Because the radial-axial ring rolling process is a large scale andncomplex metal forming process with multifactorial coupling effects, it is difficult and costly tonaccurately analyse the process by analytical or experimental methods. In this paper, a valid 3Dncoupled thermo-mechanical FE model of radial-axial ring rolling is explored using the dynamicnexplicit code ABAQUS/Explicit, and the main features of the FE model are described. Then,nbased on the valid 3D FE model, the distribution and evolution laws of the strain and temperaturenare investigated. The results obtained provide useful guidelines for further investigation of thenmechanism of formation of radial-axial ring rolling.
