A CLOSED FORM SOLUTION FOR PREDICTING SPRINGBACK IN BENDING OF BEAMS INCLUDING HARDENING EFFECT

Springback is an implicit phenomenon in most forming processes and needs to be accounted for in the design of forming tools. This is essential in order to limit the number of iterations required during the design and fabrication of forming tools and dies. This work presents a closed form solution for predicting springback in bending including hardening effect. Springback was also determined using experimental testing. The results obtained are compared with analytical results and the influence of hardening on springback is analysed.
