A general forming limit criterion for sheet metal forming
TLDR
In this article, it is shown that the forming limit for both proportional loading and non-proportional loading can be explained from a single criterion which is based on the state of stress rather than the state-of-stress.About:

Path independent limiting criteria in sheet metal forming
TL;DR: In this paper, a comparison among all common available strain path independent strain/stress based limiting criteria is presented, and the choice of yield criterion has an impact on the results for TFD, XFLD, ESRFLD and PEPSD.

An analysis of localized necking in aluminium alloy tubes during hydroforming using a continuum damage model
TL;DR: In this paper, the effect of loading conditions on tubular hydroforming was analyzed using the Marciniak-Kuczynski (M-K) method along with an anisotropic version of the Gurson model, and it was demonstrated that a transition from axial to circumferential necking occurs when high ratios of axial extension to volume flow rate are applied to the tube.

Computational analysis of stress-based forming limit curves
TL;DR: In this article, a model consisting of a homogeneous zone and a zone that has voids (material inhomogeneity) is proposed and used to simulate necking under plane strain and uni-axial stress load paths.

The strain gradient approach to predict necking in tube hydroforming
TL;DR: In this paper, a stress-based forming limit diagram for necking prediction which is based on the strain gradient theory of plasticity in conjunction with the M-K model has been represented and used in tube hydroforming.

Experimental and Numerical Determination of Limiting Drawing Ratio of Al3105-Polypropylene-Al3105 Sandwich Sheets
TL;DR: In this paper, the limiting drawing ratios (LDRs) of the sandwich sheets were determined using finite element analysis simulations by considering Gurson-Tvergaard-Needleman damage model.
