Identification of mixed hardening parameters for aluminium sheet by cyclic loading tool

This project is about identifying mixed hardening parameters of aluminium alloy AA 1100 by cyclic loading tool. The identified parameters are useful as input data in sheet metal forming simulation. It helps to improve the performance of the simulation to solve forming problem such as springback. The...
