TL;DR: In this article, the authors define a new class of sheet-bulk metal forming processes, give an overview of the existing processes belonging to this class, highlight the tooling aspects as well as the resulting product properties and present a short summary of the relevant work that has been done towards modeling and simulation.

TL;DR: The hot stamping processes of quenchable steel sheets potentially offer not only small forming load and high formability, but also high strength and no springback by die quenching.

TL;DR: In this paper, the authors provide a critical review of the models available today for predicting the material behaviour at both industrial and scientific level, and the tests needed to identify the models' material parameters.

TL;DR: In this paper, a detailed analysis of the experimental strain distribution measured by digital image correlation is discussed for each test and the applicability of each test for the observation of the material behavior under shear stress with a view to material modeling for finite element simulations.

TL;DR: In this paper, a method to include the distribution of strains in the identification of the planar anisotropy of sheet metals is proposed, which includes the optical measurement of strains on a flat specimen with a varying cross-section and an inverse parameter identification scheme which minimizes the differences between the numerical simulation results and the experimental measurements by using Levenberg-Marquardt algorithm.
