A study is made of the factors affecting the formability of corners in the stamping of sheetmetal parts. The corners are modeled by toroidal shells. The factors considered are geometry, the toroidal radii A and B, friction factor μ, strain- hardening index n, and anisotropy ratio R. The analysis is based on a new differential equation approach, where formability is associated with singularities in the differential equations. The results presented in graphical form should prove useful for design.The difference between biaxial and plane strain conditions are made, and comparisons are made with some known experimental results and other theoretical results in the literature.
