Abstract EN
In simulations of forged and stamping processes using the finite element method, load displacement paths and three-dimensional stress and strains states should be well and reliably represented.
The simple tension test is a suitable and economical tool to calibrate constitutive equations with finite strains and plasticity for those simulations.
A complex three-dimensional stress and strain states are developed when this test is done on rectangular bars and the necking phenomenon appears.
In this work, global and local numerical results of the mechanical response of rectangular bars subjected to simple tension test obtained from two different finite element formulations are compared and discussed.
To this end, Updated and Total Lagrangian formulations are used in order to get the three-dimensional stress and strain states.
Geometric changes together with strain and stress distributions at the cross section where necking occurs are assessed.
In particular, a detailed analysis of the effective plastic strain, stress components in axial and transverse directions and pressure, and deviatoric stress components is presented.
Specific numerical results are also validated with experimental measurements comparing, in turn, the performance of the two numerical approaches used in this study.
