Cold forging is the most
efficient technology for high volume production of near-net-shape and ready to
assemble components for transport, mechanical ,
electrical and other industries. In this
highly competitive industry the success depends on ability to efficiently
compute deflections that simultaneously interact in a combined workpiece-die-press system and to optimize precision of parts and
service life of tooling systems by taking into account all relevant process
parameters. Smooth contact elements and large strain plasticity elements were
used to make simulation of the two-phase forging process in the example.
Implementation of the complex scenario involved is a difficult task for most of
the commercial finite element systems. The flexibility of data manipulations in
Mathematica and the structure of AceFEM where all the data can be access and
changed directly from Mathematica is proved to be an
efficient combination for the implementation of complex scenarios.
