The application of the smoothed particle hydrodynamice (SPH) method and the experimental verification of cutting of sheet metal bundles using a guillotine

The article presents the application of the SPH method for the modeling of cutting composite bundles using a guillotine. For many years, the SPH method has been applied in the modeling of dynamic phenomena in which rapid strain and large deformations occur. The discrete model has been performed by combining the FEM and the SPH. The SPH method has only been applied for to the fragment in which the material separation during cutting appears. To verify the numerical results, experiments have been performed using a special test stand for the confirmation of the correctness of the developed model and the numerical simulations.
