摘要：
Springback is the elastic recovery of a material when it is loaded into the plastic region and then unloaded. Springback is an implicit phenomenon in bending operations. A good knowledge of springback is essential in order to limit the number of iterations required in order to fabricate forming tools and dies within specified tolerances. This work presents the results of a systematic study of springback in beams using different methods and considering different materials and thicknesses. Springback was determined using experimental testing with strain gauges, and the results obtained are compared with analytical and finite element analysis (FEA) results. Very good agreement was obtained in all cases considered.
