Two-stage forming approach for manufacturing ferritic stainless steel bipolar plates in PEM fuel cell: Experiments and numerical simulations
TL;DR: In this article, a multi-stage micro-channel forming by stamping was performed for ultra-thin ferritic stainless steel sheets with thicknesses of 0.1 and 0.075mm, as a good substitute for traditional graphite bipolar plates of proton exchange membrane fuel cell.

Crystal plasticity finite element analysis of ferritic stainless steel for sheet formability prediction
TL;DR: In this paper, a virtual microstructure crystal plasticity finite element model, or a representative volume element (RVE), was developed, in which the behavior of grains was governed by a rate-dependent viscoplastic model.

Limit strains in the processes of stretch-forming sheet metal
TL;DR: In this paper, a theoretical analysis of the process of the generation of the groove based on anisotropic plasticity theory is presented, and the system of equations derived was solved numerically with the aid of a computer, which enabled the limiting strain of the sheet metal to be determined as a function of the material.

Frédéric Barlat,Frédéric Barlat,J.C. Brem,Jeong W. Yoon,Jeong W. Yoon,Kwansoo Chung,Re Dick,D.J. Lege,Farhang Pourboghrat,Shi-Hoon Choi,E. Chu +10 more
TL;DR: In this article, a plane stress yield function that well describes the anisotropic behavior of sheet metals, in particular, aluminum alloy sheets, was proposed, which was introduced in the formulation using two linear transformations on the Cauchy stress tensor.

On discontinuous plastic states, with special reference to localized necking in thin sheets
TL;DR: In this article, the authors investigated the permitted discontinuities of stress, velocity, and surface slope in a plastic-rigid sheet deformed in its plane, and the necessary restrictions on the stress-state and rate of workhardening were obtained for any yield function and plastic potential.
