Effect of Computational Parameters on Springback Prediction by Numerical Simulation

Metals, 2017
Elastic recovery of the material, called springback, is one of the problems in sheet metal forming of drawpieces, especially with a complex shape. The springback can be influenced by various technological, geometrical, and material parameters.

Effects of Hardening Model and Variation of Elastic Modulus on Springback Prediction in Roll Forming

Metals, 2019
In this paper, the uniaxial loading−unloading−reloading (LUR) tensile test was conducted to determine the elastic modulus depending on the plastic pre-strain. To obtain the material parameters and parameter of Yoshida-Uemori’s kinematic
