Abstract:Guillotining is a sheet metal cutting process, in which the sheet is cut pro-
gressively from one end to the other. Consequently guillotining can be seen as a three-
dimensional stationary process. A finite element model is developed for the calculation of the steady state of this process. To be able to handle history dependent material pro-
perties and moving free surfaces an Arbitrary Lagrangian Eulerian formulation is used.
The position of the crack front is initially modelled and kept �xed during the calculation.
The results of a guillotining simulation are shown in this paper.
