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:

Sheet Metal Forming Limit Under Stretch-Bending
Z. Cedric Xia,Danielle Zeng +1 more
TL;DR: In this paper, a theoretical formulation for the Bending-enhanced Forming Limit Diagram (FLD) is presented, where the deformation theory of plasticity is employed for the instability analysis, and the bending is assumed only in the direction along one principal loading.

Free Expansion Bulge Testing of Tubes For Automotive Hydroform Applications
TL;DR: In this paper, a new model was developed in which simulated the whole tube instead of considering only its mid-section, judged by the pressure-expansion relations, the model accurately predicted free expansion hydroforming tests results.
