Abstract: Two finite element simulation techniques are applied for the analysis of a basic operation in LIF processes. Implicit and explicit numerical methodologies are used by Abaqus/standard and Abaqus/explicit solvers, respectively. The most suitable mesh and geometry of the punch have been chosen among different ones according to the computation time, accuracy of results and forming capability. Once the mesh and the geometry of the punch are chosen, a single operation is simulated by means of both implicit and explicit FE models. Experimental tests were also conducted. Forces and geometrical profiles were compared among those obtained by experiments and simulations and the results show good correspondence. The explicit FE model looks robust enough to use the same modelling parameters in further studies, where explicit methodology is expected to be mandatory due to multiple-strokes operations.
