Modelling of Material Flow During Incremental Forming Process on the Basis of Digital Material Representation Concept

The main goal of the work is development of the multiscale numerical model of the incremental forming process for manufacturing integral elements applicable in the aerospace industry. Description of the proposed incremental forming concept based on division of large die into a series of small anvils pressed into the material by a moving roll is presented. A complex multi scale numerical model of mentioned incremental forging process based on the digital material representation (DMR) concept was developed and is also described within the paper. Finally, obtained results in the form of strain distribution are presented and compared with the outcome from conventional forging at the macro and micro scale, respectively.
