Improvement of the Iterative Algorithm for Numerical Simulation of Springback in Sheet Metal Forming

Abstract:

Article Preview

Springback is an inevitable process of sheet metal forming phenomenon. Numerical simulation is an effective way to solve the springback problem, and more and more attention to industry and academia. This paper describes the implicit springback analysis of the BFGS equilibrium iteration method, and proposes a strategy for optimizing the calculation, reducing the computation and avoiding the potential problem of instability in the calculation. At last, the use of self-developed software gives numerical examples.
