TLDR
A review of current industrial research and development in blank-holding technology, and its effect on the formability of sheet metals is presented in this article, where it is shown how the blank-holder force and the way it is applied on the blank affects the state of stress and strain within the part, and also influences the strain path.About:

Multiobjective robust optimization method for drawbead design in sheet metal forming
TL;DR: In this paper, a multiobjective robust optimization methodology is presented to address the effects of parametric uncertainties on drawbead design, where the six sigma principle is adopted to measure the variations, a dual response surface method is used to construct surrogate model and a multi-objective particle swarm optimization is developed to generate robust Pareto solutions.

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.

Influence of the plastic properties of a material on the forming limit diagram for sheet metal in tension
TL;DR: In this article, the formation of a groove, which appears before fracture in sheet metal subject to tension, is presented, and is based on the assumption of initial nonhomogeneity of the material in order to facilitate the determination of the limit strain.
