In order to fully realize the strength potential of cold-formed parts, strain hardening and residu- al stress from the cold-forming process must be considered in structural FEA simulations of the loaded condi- tion. However, only topological data have previously been transferred when using separate forming and struc- tural-simulation tools. This paper presents a new method for transferring local residual stress and strain data from the forming simulation tool Deform3DTM to the structural analysis tool Ansys Workbench. The aim of the method is to increase the accuracy of structural-simulation results for cold-formed parts under load using sep- arate simulation tools for the cold-forming and structural behaviour of manufactured components. The appli- cation of the method is demonstrated using the example of a full-forward-extruded shaft under torsional load. Validation of the data transfer and comparison of simulated deformation behaviour of the shaft, both includ- ing and discarding residual stress and strain, are carried out.
