"Attempted substitution of new solid materials and composite metal strips for those materials presently being used in many applications now being pursued vigorously in industry. A serious problem was created because the newly proposed materials do not exhibit the same springback after bending as did the previously used materials in a particular bend angle and radius situation. Elementary bend theory and mechanical metallurgical techniques have been incorporated into a method which can be used to accurately predict the .2% offset yield strength of any proposed rolled-temper solid metal strip and some composite strips when they must exhibit the same springback angle as does the presently used material. The method considers the work hardening characteristics of the material being compared and is not sensitive to springback problems resulting from the configuration of the stress-strain curve for the materials. Materials were found to behave as their engineering stress-strain curves predicted. Differences between similar materials such as chemistry and grain size were found to be significant only as they affected the stress-strain curves"--Abstract, page ii.
