With digital-image correlation techniques, it is now possible to measure the forming-limit diagram, FLD, of metal sheet using both strains outside (Bragard-type analysis) and inside (temporal, correlation-coefficient calculation) of a necking instabi

The Marciniak-Kuczynski (MK) technique, which describes the progressive evolution of an initial imperfection and the subsequent necking of the sheet metal, has been the most popular model for the study of sheet metal formability. For at least the las

In the present work, an efficient formulation for the prediction of forming-limit diagrams (FLDs) based on the well-known Marciniak and Kuczynski (MK) theory using a Visco- Plastic Self-Consistent (VPSC) crystal-plasticity model has been detailed. Th

The formability prediction of dual-phase steel sheets is highly important in the present automotive industry. In this study, the forming-limit curve (FLC) of a DP-780 steel sheet is predicted based on the well-known Marciniak and Kuczynski (MK) theor

In this work, the influence of plastic anisotropy on forming-limit strains for a drawing-quality steel sheet was investigated. For this purpose, hourglass-type samples, taken at 0°, 45° and 90° with respect to the sheet rolling direction were test

In this research, we analyze forming-limit strains of FCC and BCC materials using a viscoplastic self-consistent polycrystal model (VPSC) in conjunction with the Marciniak–Kuczynski (MK) approach. In particular, our work is focused on the theoretic

The Forming Limit Diagrams (FLDs) of textured polycrystalline sheet metals were investigated using micro-macro averaging and two types of grain-interaction models: Full-Constraint (FC) and Self-consistent (SC) schemes, in conjunction with the Marcini

This paper explores the right-hand side of the forming limit diagram (FLD) for a BCC material in order to test the crystallographic slip assumptions. BCC crystals are considered with either 24 or 48 slip systems (BCC24 or BCC48). Identical uniaxial s

The effect on forming-limit diagrams (FLD) of an initial cube texture and its evolution was studied using the well-known M–K approach in conjunction with a viscoplastic crystal plasticity model (VPSC). We focused on how the strength of the cube tex
