NUMERICAL SIMULATION OF COMPLEX LARGE DEFORMATION PROCESSES

SUMMARY: In recent years, the development of new material models has allowed to predict the mechanical behaviour of metals in complex strain paths. In this paper, a comparative analysis of numerical results, obtained with different constitutive models, is presented. Those models were implemented in the finite element code DD3IMP, devoted to the numerical simulation of the deep-drawing process. We focus the ability of the GID application to visualize and compare the results of different mechanical models, particularly the evolution of the stress and strain fields, contact forces, displacements, etc., calculated during the numerical simulation of the deformation process.
