Modelling Aspects in Accumulative Roll Bonding process by Explicit Finite Element Analysis

Accumulative Roll-Bonding (ARB) process is a severe plastic deformation (SPD)process, capable of developing grains below 1 μm in diameter and improving mechanical propertiesof the material. In this study, the authors compared two different FE-codes with respect of itsapplicability for numerical analysis of the ARB process. Modelling this process was achieved usingthe explicit code for Abaqus/CAE both in 2D and 3D. The proposed model was used to assess theimpact of ARB cycles on the final material properties. The numerical results in 2D and 3D werecompared and contrasted. The research work presented in this paper is focused on the simulationoptimization based on CPU time minimization. The numerical simulations were also validatedthrough a comparison with the experimental results.
