Shear-dominated processes in sheet metal forming

Many critical manufacturing processes in sheet metal forming are characterized by shear-dominated mechanisms. By clearly defining how shear-dominated processes can be classified based on stress triaxiality and the Lode parameter, this paper provides an overview of their characteristics and challenges in sheet metal forming. Based on the distinction into in-plane and out-of-plane shear-dominated processes and an introduction to the mechanical fundamentals of shearing mechanics, the topics of testing and measurement methods, simulation, and tooling are discussed. Finally, concepts and principles are illustrated with specific application examples. The paper concludes with open topics and upcoming challenges.
