Abstract:

The present paper discusses possibilities of combination of the Crystal Plasticity (CP) modelling with the 3D Digital Materials Representation (DMR) approach for the simulation of the non-linear deformation processes. Application of such modelling strategy as an extension of the existing multiscale model developed for prediction of the strain inhomogeneity during processes subjected to the complex strain paths, is presented and discussed. Two metal forming processes, characterised by non-linear loading conditions i.e. Accumulative Angular Drawing (AAD) process and the cyclic torsion deformation were chosen to verify the proposed modelling strategy. It is shown that thanks to a combination of the multiscale finite element model with the DMR and CP approach, detailed information on strain inhomogeneities and texture can be accurately obtained in both investigated processes.
