[QUOTE="jrmichler, post: 6530651, member: 638574"] This diagram, from Metal Forming - Mechanics and Metallurgy by Hosford and Caddell, shows how to calculate residual stresses after plastic bending and force removal for a simple elastic-plastic material: [ATTACH type="full"]287868[/ATTACH] It is used in springs to reduce peak surface tensile stress under load. Search term [B]preset ([/B]or[B] presetting) springs[/B] to learn more. A basic calculation in sheet metal forming is to calculate the amount of springback when bending sheet metal. The above diagram is for simple bending. The calculation is even more fun when calculating bending under tension for the purpose of reducing springback. [/QUOTE]
