Alternative
Praxisrelevanter Vergleich zwischen der Finite-Elemente-Theorie und den netzfreien Berechnungsmethoden der Analyse von Zerspanungssimulationen
Abstract
In order to get a closer feeling for the simulations technologies, the present study analyzes the practical strengths and weaknesses between the calculation methods available in LS-Dyna. With the use of a standard evaluation of a machining simulation a comparison between the calculation methods FEM (Finite-Element-Method), SPH (Smoothed-Particle-Hydrodynamic) and EFG (Element-Free-Galerkin) has been conducted. Despite the similar results in relation to the cutting forces, variations on the resulting deformations, robustness and time requirements have been identified.
