Zusammenfassung:Modelling large three-dimensional metal forming deformations with the finite-element program PLAST3 is presented. The program utilises the penalty constrained method, based on the rigid-plastic flow formulation. The structure and main capabilities of this program are described. The post-processing unit PLAPOST3 utilized for the analysis of the simulation results in a graphical form is presented also, this unit being written in LISP language inside a commercial CAD package. A sample solution supported by experimental work carried out with an aluminium alloy at room temperature is included. Theoretical and experimental results are analysed, good agreement between them being found.
