A series of tests were performed to determine the influence of curvature on the forming limits of 1008 AK steel. Rectangular blanks cut from three thicknesses of the material from 0.69 mm to 1.04 mm were securely clamped at opposite edges and stretched over wedge shaped punches of different radii. A series of punches were used with radii that varied from 0.508 mm to 12.7 mm to produce bending effects that range from severe to mild. Measurements show that the neck forms on the convex surface when the strain on the concave side of the sheet reaches a value consistent with the forming limit in plane-strain for in-plane deformation.
