Strain hardening response and modeling of EDDQ and DP780 steel sheet under non-linear strain path
TL;DR: In this article, the anisotropic hardening behaviors of dual phase (DP780) and extra deep drawing quality (EDDQ) steel sheets under non-proportional strain paths were investigated.
Journal ArticleDOI
Strain-path change induced transients in flow stress, work hardening and r-values in aluminum
TL;DR: In this article, a continuum plasticity model was developed that can reproduce the observed behavior and was implemented into the finite element software LS-DYNA to simulate early strain localization subsequent to an orthogonal strain-path change.

Experimental and numerical study of reverse re-drawing of anisotropic sheet metals
TL;DR: In this paper, a reverse re-drawing of cylindrical cups was performed on a classical tensile test machine with a maximum load of 100kN, where both the dynamic explicit finite element code Pam-Stamp and the static implicit home code DD3IMP were used.

Finite Element Analysis of Multi-Stage Deep Drawing Process for High Precision Rectangular Case with Extreme Aspect Ratio
TL;DR: In this article, a finite element analysis for multi-stage deep drawing process for high-precision rectangular cases is carried out especially for an extreme aspect ratio, which shows that the irregular contact condition between blank and die affects the occurrence of failure, and the difference of aspect ratio in the drawn section leads to nonuniform metal flow, which may cause failure.

S. A. Majlessi,D. Lee +1 more
TL;DR: In this paper, a multistep sheet metal forming process for axisymmetric shapes has been modeled employing a simplified finite element analysis method, based on the idea of dividing the deformation history into several steps while applying the total strain theory of plasticity in each step.

Consideration of the re-drawing of sheet metals based on finite-element simulation
TL;DR: In this article, the effects of the work-hardening characteristics of blank material, the first-stage drawing ratio, the tool shape and interstage annealing on the limiting re-drawing ratio have been considered, based on the results of the rigid-plastic finite-element simulation of the direct and reverse redrawing processes.
