An analysis of the current literature suggests that the main difficulty in modelling guillotining is that only a limited number of FEM models are currently capable of describing the complete shearing process, including the complete separation of the material parts through ductile fracturing.
In this paper, the guillotining process is considered an initial and boundary value problem with geometrical, physical and thermal nonlinearity and with only partial knowledge of the boundary conditions.
In the next section, this model is used for the variational formulation of a nonlinear equation of motion for the guillotining operation.
In this paper, this method is used to model the guillotining process.
A three-dimensional finite element model of guillotining is presented in Figs.
4 shows the evolution of the guillotining force compared to the upper knife penetration.
