Analytical Approach of Springback of Arced Thin Plates Bending

In practical production, metal sheet bending process contains multiple steps of bending to meet the requirements of the shape and quality. The arced thin plate with pre-strain is taken as the subject to investigate the subsequent bending and spring-back. Based on linear combined hardening constitutive model, the analytical method of the arced thin plate with pre-strain bending forming and springback is researched. The tangential strain on the...
